DATA SHEET AAT1147 High Efficiency, Low Noise, Fast Transient 400mA Step-Down Converter General Description The AAT1147 SwitchReg is a member of Skyworks' Total Power Management IC™ (TPMIC™) product family. It is a fixed frequency 1.4MHz step-down converter with an input voltage range of 2.7V to 5.5V and output voltage as low as 0.6V. The AAT1147 is optimized for low noise portable applications, reacts quickly to load variations, and reaches peak efficiency at heavy load. The AAT1147 output voltage is programmable with external feedback resistors. It can deliver 400mA of load current while maintaining high power efficiency. The 1.4MHz switching frequency minimizes the size of external components while keeping switching losses low. The AAT1147 is available in a Pb-free, space-saving 2.0x2.1mm SC70JW-8 package and is rated over the -40°C to +85°C temperature range. Features • VIN Range: 2.7V to 5.5V • VOUT Adjustable from 0.6V to VIN • 400mA Output Current • Up to 98% Eff.
