AAT1149B 2.2MHz Fast Transient 400mA Step-Down Converter

The AAT1149B SwitchReg is a 2.2MHz step-down converter with an input voltage range of 2.2V to 5.5V. It is optimized to react quickly to load variations and operate with a tiny 0603 inductor that is only 1mm tall. The AAT1149B can deliver 400mA of load current while maintaining a low 45μA no load qui.

AAT1149B Features

* Ultra-Small 0603 Inductor (Height = 1mm)

* VIN Range: 2.2V to 5.5V

* VOUT Fixed 1.8V

* 400mA Max Output Current

* Up to 98% Efficiency

* 45μA No Load Quiescent Current
