Product Overview
TPS65217 is a Texas Instruments single-chip PMIC for battery-powered systems, with stated support for Sitara AM335x portable and 5-V line-powered applications. The device integrates power-path operation for USB, 5-V AC adapter, or Li-ion battery sources, and the USB and AC inputs are 20 V tolerant.
The regulator structure includes three DCDC converters with integrated switching FETs, fixed 2.25 MHz switching frequency, ±2% output voltage accuracy in PWM mode, 100% duty-cycle operation for lowest dropout, and 15 µA typical quiescent current per converter. It also includes two adjustable LDOs, with LDO2 configurable to track DCDC3, plus two independent load switches where LDO3 and LDO4 are configurable as LDOs.
The PMIC is packaged in a 48-pin VQFN (RSL), 6.00 mm x 6.00 mm body with 0.4 mm pitch and an exposed thermal pad. Control and protection functions include I2C address 0x24, password-protected I2C registers, undervoltage lockout, a battery fault comparator, an always-on push-button monitor, and active-low nRESET shutdown behavior.
