N6200 - NIKO-SEM

N6200 Step-Down Converter

N6200 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 N6200 can supply 600mA of load current fro.
