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.
