AX3531, 2A Synchronous Step-Down Converter

AX3531 1.25MHz, 2A Synchronous Step-Down Converter  GENERAL .
AX3531 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture.

Features

* 2.8V to 5.5V Input Voltage Range Output Voltage from 0.6V to VIN High Efficiency: Up to 96% 1.25MHz Constant Frequency Operation Up to 2A Output Current Quiescent Current: 200uA (Typical) No Schottky Diode Required Current Mode Operation for Excellent Line and Load Transient Response Current limit,

Applications

* 100% duty cycle provides low dropout operation, extending battery life in portable systems. Switching frequency is internally set at 1.25MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and decreases need of an external scho
