Description:

1A Synchronous Step-Down Converter

Features

* 2.5V to 6V Input Voltage Range High Efficiency: Up to 94% 1.5MHz Constant Frequency Operation 1A Output Current at VIN=3.6V and VOUT=1.8V Quiescent Current: 35uA (input < 4.2V) No Schottky Diode Required 100% Duty Cycle in Dropout 0.6V Reference Allows Low Output Voltages Current Mode Operation for

Applications

* 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors
