LP8725 - Power Management

General Description

This device is a multi-function, programmable Power Management Unit (PMU), optimized for sub block power solutions.

Key Features

  • programmable power-on sequencing. LDO regulators provide high PSRR and low noise ideally suited for supplying power to both analog and digital loads. The device can be configured either as a Sub_PMU for modules (for example, camera/multimedia modules) or as a stand-alone PMU that powers the processor itself. “Notice: This document is not a datasheet.

LP8725 PRODUCT BRIEF LP8725 PRODUCT BRIEF December 1, 2009 Power Management Unit for Application/Multimedia Processors and Sub-Systems General Description This device is a multi-function, programmable Power Management Unit (PMU), optimized for sub block power solutions. This device integrates two highly efficient 600 mA step-down DC/DC converters configurable up to 800 mA load with Dynamic Voltage Scaling (DVS) through an I2C, two low noise analog LDOs, three digital LDOs for up to 300 mA load current each, two Low Input Low Output (LILO) regulators and an I2C-compatible serial interface to allow a host controller access to the internal control registers. The device also features programmable power-on sequencing.
