AP2406, 600mA Synchronous Step-Down Converter

AP2406 Chipown 1.5Mhz, 700mA Synchronous Step-Down Converter Description The AP2406 is a high efficiency monolithic synchronous buck regulator using

Features

* z High Efficiency: Up to 96% z 1.5MHz Constant Switching Frequency z 700mA Output Current at VIN=3V z Integrated Main switch and synchronous rectifier. No Schottky Diode Required z 2.5V to 6.5V Input Voltage Range z Output Voltage as Low as 0.6V z 100% Duty Cycle in Dropout z Quiescent Current: 300µ

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
