AX3700, VFB=0.6V Synchronous Step-Down Converter

AX3700 1.4MHz, 600mA, VFB=0.6V Synchronous Step-Down Converter  GENERAL .
AX3700 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 600mA 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 Op

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
