AAT2603 Datasheet | Skyworks Solutions

DATA SHEET Total Power Solution for Portable Applications General Description The AAT2603 is a highly integrated power management solution for handheld mobile systems. It provides six regulated voltages from a single-cell Lithium-ion/polymer battery or a 5V supply. The six outputs are produced by six regulators; two switching step-down regulators and four low-dropout (LDO) regulators. Each voltage regulator has its own independent enable pin. The high efficiency step-down regulators are fully integrated and switch at a high 1.5 MHz fixed frequency. They automatically transition to variable frequency operation at light loads for improved efficiency. DC-DC1 (Buck1) is designed for...
