AAT3608 - Compact Seven-Channel Regulator

General Description

The AAT3608 is a member of Skyworks' Total Power Management IC (TPMIC™) product family.

Key Features

  • deep sleep mode operation. The step-down regulators are monolithic synchronous converters integrating the compensation network and soft start circuitry. The 1.5MHz operating frequency enables the use of tiny 2.2μH inductors and small 4.7μF output capacit.

DATA SHEET AAT3608 Compact Seven-Channel Regulator with Li+/Polymer Linear Battery Charger and I2C Interface General Description The AAT3608 is a member of Skyworks' Total Power Management IC (TPMIC™) product family. It contains a single-cell lithium ion/polymer battery charger, two 800mA switching regulators, and five low dropout (LDO) regulators in a small Pb-free 40-pin 5mmx5mm TQFN package, making it ideal for portable space-constrained systems. The single-input linear charger powers up from an adapter or a USB port. The adapter charge current is programmable with an external resistor or pin selectable between 100mA and 500mA when connected to a USB port. The device integrates a load switch for dynamic power path and features deep sleep mode operation.
