LP5552 Datasheet Pwi 2.0 And Powerwise Technology Compliant Energy Management

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LP5552 PWI 2.0 and PowerWise™ Technology pliant Energy Management Unit ADVANCE INFORMATION September 2006 LP5552 PWI 2.

General Description

The LP5552 is a PWI 2.0 pliant Energy Management System for reducing power consumption of stand-alone mobile phone processors such as base-band or applications processors.

The LP5552 contains two advanced, digitally controlled switching regulators for supplying variable voltage to processor core and memory.

The device also incorporates 5 programmable LDO regulators for powering I/O, peripheral logic blocks, maintaining memory retention (dual-domains) in shutdown mode, and auxillary functions.

Key Features

  • n Two 800 mA buck regulators operate 180 degrees out of phase for reduced EMI n 3.6 MHz PWM switching frequency n Five programmable LDOs ideal for I/O , PLL, and memory retention supply generation. n Supports high-efficiency PowerWise Technology Adaptive Voltage Scaling n PWI 2.0 open standard interface for system power management n Digitally controlled intelligent voltage scaling n Auto or PWI controlled PFM mode transition n Internal soft start/startup sequencing. n Power OK output.
