Product Overview
The TPS61252 is a Texas Instruments adjustable boost converter for Power_Management designs requiring conversion from a 2.3 to 6.0 V input rail to a 3.0 to 6.5 V output rail. Its output is adjustable up to 6.5 V, and the feedback reference is specified at 1.182 V minimum, 1.2 V typical, and 1.218 V maximum under the stated 3.6 V input and 5.0 V output condition.
The converter operates at a typical 3.25 MHz oscillator frequency and reaches up to 92% efficiency. It includes a programmable valley switch current limit from 100 to 1500 mA set by RILIM, with ±20% input current limit accuracy at 500 mA over temperature. Protection and control functions include shutdown load disconnect, reverse-current protection, short-circuit protection, UVLO, input overvoltage protection, thermal shutdown, enable input control, and open-drain power-good output.
The device is offered in an 8-pin WSON (DSG) package with a 2.00 mm x 2.00 mm nominal body. Recommended operating ranges include -40°C to 85°C free-air temperature and -40°C to 125°C junction temperature. The typical application uses a 1 µH inductor, 10 µF input capacitor, and 22 µF output capacitor for a 5.0 V output configuration.
