LP3972  
Power Management Unit for Advanced Application  
Processors  
General Description  
Features  
The LP3972 is a multi-function, programmable Power Man-  
agement Unit, designed especially for advanced application  
processors. The LP3972 is optimized for low power handheld  
applications and provides 6 low-dropout, low-noise linear reg-  
ulators, three DC/DC magnetic buck regulators, a back-up  
battery charger and two GPIO’s. A high speed serial interface  
is included to program individual regulator output voltages as  
well as on/off control.  
Compatible with advanced applications processors  
requiring DVM (Dynamic Voltage Management)  
Three buck regulators for powering high current processor  
functions or I/O's  
6 LDO's for powering RTC, peripherals, and I/O's  
Backup battery charger with automatic switch for lithium-  
manganese coin cell batteries and Super capacitors  
I2C compatible high speed serial interface  
Software control of regulator functions and settings  
Precision internal reference
