The TPS659121 is a PMU chip from TI that is designed for processor power. It has four configurable step-down converters that can provide up to 2.5A of output current for memory, processor core, I/O or pre-regulation of LDOs. It also includes 10 LDO regulators for external use.
The TPS659121 is a Power Management Unit (PMU) designed to provide configurable step-down converters with up to 2.5A output current for memory, processor core, I/O, or pre-regulation of LDOs. It also integrates ten Low Dropout (LDO) regulators that can be supplied from either a battery or a pre-regulated supply.
The device includes an independent automatic Voltage Scaling interface allowing transitions to different voltages via I2C or basic control. It features three integrated RGB LEDs with advanced dimming capabilities and supports flexible power-up/power-down sequencing based on OTP settings. The chip is available in a 9x9 ball x 9 ball WCSP package.
