Product Overview
The TPS65916 is a Texas Instruments Power_Management PMIC intended for systems that require multiple configurable supply rails, state sequencing, and digital control. Its operating system supply range is 3.135 V to 5.25 V, with off-mode current consumption of 20 uA and sleep-mode current consumption of 90 uA when two SMPS regulators remain active.
The power architecture includes five integrated step-down SMPS regulators and five LDO regulators. The SMPS outputs are configurable from 0.7 V to 3.3 V in 10 mV or 20 mV steps, with two standalone 3.5 A regulators that can combine for 7 A dual-phase operation. Additional SMPS current capabilities are 3 A, 2 A, and 1.5 A. LDO outputs span 0.9 V to 3.3 V in 50 mV steps, including two 300 mA LDOs with bypass mode, one low-noise LDO, and two 200 mA LDOs.
System functions include OTP-configured power-up, power-down, and SLEEP-to-ACTIVE sequences, three digital startup outputs, SPI and dual I2C interfaces, watchdog monitoring, ADC-based voltage, current, die-temperature, and external-voltage monitoring, plus high-temperature warning and thermal shutdown. The device is supplied in a VQFN-48 package with a nominal 7.00 mm x 7.00 mm body.
