SC1578 HIGH-EFFICIENCY STEP-DOWN DC-DC CONVERTER

The SC1578 is a high performance step-down DC-DC converter, designed to drive an external P-channel MOSFET to generate programmable output voltages. Two main schemes of pulse-skipping and pulsefrequency modulation are employed to maintain low quiescent current and high conversion efficiency over wid.

SC1578 Features

* 4V to 24V input voltage operation.

* High efficiency (up to 95%).

* Low quiescent current at 90µA.

* Pulse-skipping and pulse-frequency modulation.

* Inputs-uncommitted current sense comparator.

* Duty cycle adjustable

* 90kHz to 280kHz oscil
