CE8509 Datasheet | Chipower

1.5MHz 600mA Synchronous Step-Down Converter CE8509 Series - INTRODUCTION: The CE8509 is a 1.5MHz constant frequency, slope pensated current mode PWM synchronous step-down converter. High switching frequency allows the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. It is ideal for powering portable equipment which runs from a single cell Lithium-Ion battery. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Low output voltages are easily supported with the 0.6V feedback reference voltage. - Features : z High efficiency : Up to 96%...
