CE8501 1.5MHz 600mA Synchronous Step-Down Converter

1.5MHz 600mA Synchronous Step-Down Converter with Low Quiescent Current CE8501 Series INTRODUCTION: The CE8501 is a 1.5MHz constant frequency, slope compensated current mode PWM synchronous step-down converter. 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. In power saving mode, 40μA quiescent current is very suitable for DSP/MCU in standby opera.
