The LP5552 power management IC supports AVS to enable the processor to adaptively adjust its supply voltage to the minimum level needed, and the LP3919 power management IC is suited for powering baseband functions. Offered in a 36-bump micro SMD package, the LP5552 includes two 800-mA buck regulators and five LDOs.
Housed in a 49-bump micro SMD package, the LP3919 contains a Li-ion battery charger, nine LDOs, two buck regulators, a USB transceiver, two comparators, and a high-speed serial interface to program on/off conditions and output voltages of individual regulator, and to read status information of the PMU. (Ea/1,000: LP5552, $4.50; LP3919, $2.35available now.)
