Product Summary
The LP8725TLE-A is a multi-function, programmable Power Management Unit (PMU), optimized for sub block power solutions. This device LP8725TLE-A 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 LP8725TLE-A also 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 applications of the LP8725TLE-A include Multi-media Processors and Portable Handheld Products.
