338-MAPBGA

The 900844 is a high efficiency Power Management Integrated Circuit

(PMIC) capable of providing operating voltages for Ultra-mobile

platforms for Netbook, Tablets, and embedded devices through its 20

voltage rails. It has 5 switching power supplies running at frequencies

from 1.0 to 4.0 MHz,14 highly efficient LDOs, and one 3.3 V power

switch. It incorporates a 10-bit ADC, Real Time Clock, 8 GPIOs and 8

GPOs.

ORDERING INFORMATION

Package

The 900844 is fully configurable and controllable through its SPI

interface. It provides an optimized power management solution for ultra-

mobile platforms used on netbooks, tablets, and slates.

Optimum partitioning, high feature integration, and state-of-the-art

technology, allow Freescale to effectively serve this growing market

segment.
