Product Overview
The TPS65912 is a Texas Instruments PMU for processor power in the Power_Management category. It combines four integrated configurable DC-DC step-down converters with ten LDO regulators for processor, memory, I/O, RF, and preregulated supply rails. The step-down converters operate from a 2.7 V to 5.5 V VIN range, support output current up to 2.5 A, provide ±2% output voltage accuracy in PWM mode, and support 100% duty-cycle operation for lowest dropout operation.
The regulator set includes eight general-purpose LDOs adjustable from 0.8 V to 3.3 V and two low-noise RF LDOs adjustable from 1.6 V to 3.3 V. The functional block data lists individual LDO current ratings from 100 mA to 300 mA, with LDO4 and LDO5 identified as low-noise 250 mA regulators.
System functions include three LED outputs multiplexed with GPIOs, up to 20 mA per LED current sink, I2C, power I2C, and SPI interfaces, OTP-based flexible power-up and power-down sequencing, a 32 kHz RC oscillator, one SLEEP pin, and long button-press detection. The package is an 81-pin YFF DSBGA with a 3.6 mm x 3.6 mm body.
