DESCRIPTION

FEATURES

The XX1188 power-management IC (PMIC) is an complete,

efficient, compact devices suitable for 3G cellular

applications such as wireless data cards, handsets and

PDAs,. It integrates a 2MHz synchronous buck regulator,

nine low-dropout linear regulators (LDOs), a RESET

generator, and an 32KHZ crystal driver and buffer.



Buck converter for MSMC,1.2V/500mA

LDO1 for MSME, 1.8V/300mA

LDO2 for MSMP, 2.6V/300mA

LDO3 for MEMA, 2.6V/300mA

LDO4 for TCXO, 2.85V/50mA

LDO5 for RFTX, 2.1V/300mA

LDO6 for RFRX, 2.7V/150mA

LDO7 for USB, 3.3V/50mA

XX1188 is housed in a thin QFN4x4-28pin package.

LDO8 for URIM, 3.0v/1.8v, 50mA

LDO9 for MMC, 3.0V/150mA

Independent ON/OFF control for LDO4,5,6,7,8,9

RESET generator
