Overview: LP8720 One Step-Down DC/DC and Five Linear Regulators with I2C patible Interface November 30, 2009 LP8720 One Step-Down DC/DC and Five Linear Regulators with I2C patible.

General Description

The LP8720 is a multi-function, programmable Power Management Unit, optimized for sub block power requirement solution.

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 I2C-patible interface to allow a host controller access to the internal control registers of the LP8720.
