FEATURES  
DESCRIPTION  
The LP5550 is  
Management System  
consumption of stand-alone mobile phone processors  
such as base-band or applications processors.  
a
PWI 1.0 compliant Energy  
for reducing power  
2
•
Supports High-Efficiency PowerWise  
Technology Adaptive Voltage Scaling  
•
PWI Open Standard Interface for System  
Power Management  
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.

•
Digitally Controlled Intelligent Voltage Scaling  
1 MHz PWM Switching Frequency  
Auto or PWI Controlled PFM Mode Transition  
Internal Soft Start/Startup Sequencing  
3 Programmable LDOs for I/O, PLL, and  
Memory Retention Supply Generation  
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.
