| FEATURES | APPLICATIONS |
| Efficiency > 90% at Nominal Operating " | USB Wireless Modems " |
| Conditions | Portable USB peripherals " |
| Programmable Average Input Current Limits " | Handheld Computers " |
| for USB Applications � 50mA to 300mA for Low Current Limit | DESCRIPTION |
| Range | The TPS6275x device is a highly efficient |
| � 300mA to 1.3A for High Current Limit Range � ±10% Current Accuracy Stable Output Voltage for Load Transients to Minimize Overshoot at Load Step Response " Hot Plug and Reverse Current Protection " | synchronous step down dc-dc converter optimized for USB powered portable applications. It can provide up to 1300mA average input current and is ideal for applications connected to a USB host. With an input voltage range of 2.9 V to 6.0V, the device supports batteries with extended voltage range and is ideal for powering USB applications |
| Automatic PFM/PWM Mode transition " | where USB compliance is required. |
| (TPS62750) Forced PWM for Noise Sensitive Applications (TPS62751) " | The TPS62750 operates at 2.25-MHz fixed switching frequency and enters Power Save Mode operation at light load currents to maintain high efficiency over the |
| VIN Range From 2.9V to 6V " Adjustable VOUT From 0.8V to 0.85×VIN " Softstart for Inrush Current Prevention " | entire load current range. The TPS62751 operates in Forced PWM mode allowing use in applications that are noise sensitive. An output discharge allows the load to discharge in shutdown. |
| 2.25 MHz Fixed Frequency Operation " Short Cicruit and Thermal Shutdown " | The 10% accurate average input current limit can be programmed with an external resistor, allowing use in |
| Protection | applications such as USB, where the current drawn |
| Available in a 2.5 × 2.5 10 pin SON Package " | from the bus must be limited to 500mA. |
The TPS6275x allows the use of small inductors and
capacitors to achieve a small solution size. The
TPS6275x is available in a 2,5mm × 2,5mm 10-pin
SON package.
