CE8506

1.5MHz 600mA Synchronous Step-Down Converter CE8506 Series „ INTRODUCTION: The CE8506 is a 1.5MHz constant frequency, slope compensated 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% z Output Current: 600mA (Typ.) z 1.5MHz Constant Switching Frequency z No Schottky Diode Required z Input Voltage: 2.5V to 5.5V z 0.6V Reference Allows Low Output Voltage z Low Dropout: 100% duty Cycle z Low Quiescent Current: 270μA z Shutdown Current: <1μA z Current Mode Operation for Excellent ...
