DESCRIPTION/ORDERING INFORMATION
This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital
switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails,
with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the VCCA supply, and the B
ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. This allows the support of
both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the
1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly
reduces the power-supply quiescent current consumption.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

DESCRIPTION
The TPS6211x devices are a family of low-noise
synchronous step-down dc-dc converters that are
ideally suited for systems powered from a 2 to 4-cell
Li-ion battery or from a 12-V or 15-V rail.
The TPS6211x is a synchronous PWM converter with
integrated N- and P-channel power MOSFET
switches. Synchronous rectification is used to
increase efficiency and to reduce external component
count. To achieve highest efficiency over a wide load-
current range, the converter enters a power-saving,
pulse-frequency modulation (PFM) mode at light load
currents. Operating frequency is typically 1 MHz,
allowing the use of small inductor and capacitor
values. The device can be synchronized to an
external clock signal in the range of 0.8 MHz to
1.4 MHz. For low-noise operation, the converter can
be operated in PWM-only mode. In the shutdown
mode, the current consumption is reduced to less
than 2 µA. The TPS6211x is available in the 16-pin
(RSA) QFN package, and operates over a free-air
temperature range of –40°C to 85°C.

DESCRIPTION
The TPS6211x devices are a family of low-noise
synchronous step-down dc-dc converters that are
ideally suited for systems powered from a 2 to 4-cell
Li-ion battery or from a 12-V or 15-V rail.
The TPS6211x is a synchronous PWM converter with
integrated N- and P-channel power MOSFET
switches. Synchronous rectification is used to
increase efficiency and to reduce external component
count. To achieve highest efficiency over a wide load-
current range, the converter enters a power-saving,
pulse-frequency modulation (PFM) mode at light load
currents. Operating frequency is typically 1 MHz,
allowing the use of small inductor and capacitor
values. The device can be synchronized to an
external clock signal in the range of 0.8 MHz to
1.4 MHz. For low-noise operation, the converter can
be operated in PWM-only mode. In the shutdown
mode, the current consumption is reduced to less
than 2 µA. The TPS6211x is available in the 16-pin
(RSA) QFN package, and operates over a free-air
temperature range of –40°C to 85°C.

The TPS6122x family devices provide a power-supply solution for products powered by either a single-cell,
two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents
depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic controller topology
using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of
the adjustable version can be programmed by an external resistor divider, or is set internally to a fixed output
voltage. The converter can be switched off by a featured enable pin. While being switched off, battery drain is
minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm x 2 mm to enable small
circuit layout size.

DESCRIPTION
The TPS54620 in thermally enhanced 3.5mm x 3.5mm QFN package is a full featured 17V, 6A synchronous step
down converter which is optimized for small designs through high efficiency and integrating the high-side and
low-side MOSFETs. Further space savings are achieved through current mode control, which reduces
component count, and by selecting a high switching frequency, reducing the inductor's footprint.
The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand alone
power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and
the open drain power good pins.
Cycle by cycle current limiting on the high-side FET protects the device in overload situations and is enhanced
by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit
which turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part
when die temperature exceeds thermal shutdown temperature.

LM118/LM218/LM318
Operational Amplifiers
General Description
The LM118 series are precision high speed operational amplifiers
designed for applications requiring wide bandwidth
and high slew rate. They feature a factor of ten increase in
speed over general purpose devices without sacrificing DC
performance.
The LM118 series has internal unity gain frequency compensation.
This considerably simplifies its application since no
external components are necessary for operation. However,
unlike most internally compensated amplifiers, external frequency
compensation may be added for optimum performance.
For inverting applications, feedforward compensation
will boost the slew rate to over 150V/μs and almost
double the bandwidth. Overcompensation can be used with
the amplifier for greater stability when maximum bandwidth
is not needed. Further, a single capacitor can be added to
reduce the 0.1% settling time to under 1 μs.
The high speed and fast settling time of these op amps make
them useful in A/D converters, oscillators, active filters,

LF198/LF298/LF398, LF198A/LF398A Monolithic Sample-and-Hold Circuits
LF198/LF298/LF398, LF198A/LF398A
Monolithic Sample-and-Hold Circuits
General Description
The LF198/LF298/LF398 are monolithic sample-and-hold
circuits which utilize BI-FET technology to obtain ultra-high
dc accuracy with fast acquisition of signal and low droop
rate. Operating as a unity gain follower, dc gain accuracy is
0.002% typical and acquisition time is as low as 6 μs to
0.01%. A bipolar input stage is used to achieve low offset
voltage and wide bandwidth. Input offset adjust is accomplished
with a single pin, and does not degrade input offset
drift. The wide bandwidth allows the LF198 to be included inside
the feedback loop of 1 MHz op amps without having stability
problems. Input impedance of 1010W allows high
source impedances to be used without degrading accuracy.
P-channel junction FET’s are combined with bipolar devices
in the output amplifier to give droop rates as low as 5 mV/min
with a 1 μF hold capacitor. The JFET’s have much lower
noise than MOS devices used in previous designs and do
not exhibit high temperature instabilities. The overall design
guarantees no feed-through from input to output in the hold
mode, even for input signals equal to the supply voltages.
Features
n Operates from ±5V to ±18V supplies
n Less than 10 μs acquisition time
n TTL, PMOS, CMOS compatible logic input
n 0.5 mV typical hold step at Ch = 0.01 μF
n Low input offset
n 0.002% gain accuracy
n Low output noise in hold mode
n Input characteristics do not change during hold mode
n High supply rejection ratio in sample or hold
n Wide bandwidth
n Space qualified, JM38510
Logic inputs on the LF198 are fully differential with low input
current, allowing direct connection to TTL, PMOS, and
CMOS. Differential threshold is 1.4V. The LF198 will operate
from ±5V to ±18V supplies.
An “A” version is available with tightened electrical
specifications.

LM3421, LM3423
N-Channel Controllers for Constant Current LED Drivers
General Description
The LM3421/LM3423 devices are versatile high voltage LED
driver controllers. With the capability to be configured in a
Buck, Boost, Buck-Boost (Flyback), or SEPIC topology, and
an input operating voltage rating of 75V, these controllers are
ideal for illuminating LEDs in a very diverse, large family of
applications.
Adjustable high-side current sense with a typical sense voltage
of 100mV allows for tight regulation of the LED current
with the highest efficiency possible. Output LED current regulation
is based on peak current-mode control with predictive
Off-Time Control. This method of control eases the design of
loop compensation while providing inherent input voltage
feed-forward compensation.
The LM3421/LM3423 include a high-voltage startup regulator
that operates over a wide input range of 4.5V to 75V. The
internal PWM controller is designed for adjustable switching
frequencies of up to 2.0MHz, thus enabling compact solutions.
Additional features include: “zero” current shutdown,
precision reference, logic compatible DIM input suitable for
fast PWM dimming, cycle-by-cycle current limit, and thermal
shutdown.
The LM3423 also includes an LED output status flag, a fault
flag, a programmable fault timer, and a logic input to select
the polarity of the dimming output driver.
