PRODUCT SUMMARY
CX20460 Power Management Integrated Circuit for GSM and GPRS Applications
Applications
* GSM and GPRS handsets/data modules
Description
Skyworks Power Management Integrated Circuit (PMIC) integrates all the power supply and battery charging functions of a low power wireless system into one package. The device is designed for Global System for Mobile communications (GSM) and General Packet Radio Service (GPRS) cellular handset applications. The CX20460 PMIC is easily programmable using a two-wire serial interface to ensure maximum flexibility for a wide variety of designs. The device provides the following functions: * Voltage switching, conversion, and regulation * Power management control logic * Charging and monitoring of system battery * SIM interface The device is packaged in a 48-pin 7.0 x 7.0 mm Land Grid Array (LGA). The LGA includes a downset paddle, which should be connected to the board ground plane. * CX20460-11 with a 1.20 mm chip height (For previous designs). * CX20460-12 with a 1.00 mm chip height * CX20460-32 with a 1.00 mm chip height The CX20460 PMIC block diagram is shown in Figure 1. The device package is shown in Figure 2 through Figure 4.
