National semiconductor LP5550 PowerWise Technology Compliant Energy Management Unit handbook

Update: 01 October, 2023

The LP5550 is a PWI 1.0 compliant Energy Management System for reducing power consumption of stand-alone mobile phone processors such as base-band or applications processors. The LP5550 contains an advanced, digitally controlled switching regulator for supplying variable voltage to processor core and memory. The device also incorporates 3 programmable LDO-regulators for powering I/O, PLLs and maintaining memory retention in shutdown-mode. The device is controlled via the PWI open-standard interface. The LP5550 operates cooperatively with PowerWise technology compatible processors to optimize supply voltages adaptively over process and temperature variations or dynamically using frequency/voltage pre-characterized look-up tables.
