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.
