Overview
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 operation; and in active mode, low output ripple voltage is good enough for noise sensitive applications.
The two modes can be automatically switched according to the load current.
