AX3701, VFB=0.6V Synchronous Step-Down Converter

AX3701 1.4MHz, 1.2A, VFB=0.6V Synchronous Step-Down Converter  GENERAL .
AX3701 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture.

Features

* 2.5V to 7.5V Input Voltage Range Output Voltage from 0.6V to VIN High Efficiency: Up to 92% 1.4MHz Constant Frequency Operation 1.2A Output Current Quiescent Current: 200uA (input < 4.2V) No Schottky Diode Required 100% Duty Cycle in Dropout 0.6V Reference Allows Low Output Voltages Current Mode Ope

Applications

* 100% duty cycle provides low dropout operation, extending battery life in portable systems. Pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.4MHz, allowing the use of small surface mount inductors and
