LP8720 Description
The LP8720 is a multi-function, programmable Power Management Unit, optimized for sub block power requirement solutions. This device integrates one highly efficient 400 mA step-down DC-DC converter with Dynamic Voltage Scale (DVS), five low-noise low dropout (LDO) voltage regulators, and a 400 KHz I2Cpatible interface to allow a host controller access to the internal control registers of the LP8720.
