1 / 42 page  LP3971 Power Management Unit for Advanced Application Processors General Description The LP3971 is a multi-function, programmable Power Man- agement Unit, designed especially for advanced application processors. The LP3971 is optimized for low power hand- held applications and provides 6 low dropout, low noise linear regulators, 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. Key Specifications Buck Regulators n Programmable V OUT from 0.8 to 3.3V n Up to 95% efficiency n Up to 1.6A output current n ± 3% output voltage accuracy LDO’s n Programmable V OUT of 1.0V–3.3V n ± 3% output voltage accuracy n 150/300/370 mA output currents — LDO RTC30mA — LDO 1 300 mA — LDO 2 150 mA — LDO 3 150 mA — LDO 4 150 mA — LDO 5 370 mA n 100 mV (typ) dropout Features n Compatible with advanced applications processors requiring DVM (Dynamic Voltage Management) n Three buck regulators for powering high current processor functions or I/O’s n 6 LDO’s for powering RTC, peripherals, and I/O’s n Backup battery charger with automatic switch for lithium-manganese coin cell batteries and Super capacitors n I 2C compatible high speed serial interface n Software control of regulator functions and settings n Precision internal reference n Thermal overload protection n Current overload protection n Tiny 40-pin 5x5 mm LLP package Applications n PDA phones n Smart phones n Personal Media Players n Digital cameras n Application processors — Intel Xscale — Freescale — Samsung January 2006 © 2006 National Semiconductor Corporation DS201807 www.national.com |
