Description

The LP5551 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 LP5551 contains two advanced, digitally controlled switching regulators for supplying variable voltage to processor core and memory. Two regulators provide P- and N- well biasing for threshold scaling applications. The device also integrates 4 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 LP5551 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 and provides P- and N-well biasing for threshold scaling.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LP5551SQ	CMOS7	0	16561	0	0	954000	4	270700104
LP5551SQX	CMOS7	0	16561	0	0	954000	4	270700104

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
