AP2406ES5-1.2

Chipown AP2406 AP2406 1.5Mhz, 600mA Synchronous Step-Down Converter Description The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The AP2406 can supply 600mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The AP2406 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads provides very low output ripple voltage for noise sensitive applications. The AP2406 is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V Applications Cellular and Smart Phones Microprocessors and DSP Core Supplies Wireless and DSL Modems PDAs MP3 Player Digital Still and Video Cameras Portable Instruments Features High Efficiency: Up to 96% 1.5Mhz Constant Switching Frequency 600mA Output Current at VIN=3V Integrated Main switch and synchronous rectifier. No Schottky Diode Required 2.5V to 5.5V Input Voltage Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout Low Quiescent Current: 300µA Slope Compensated Current Mode Control for Excellent Line and Load Transient Response Short Circuit Protection Therm...
