SC2618 - Miniature PWM Controller for Buck Regulator

General Description

The SC2618 is a hysteretic mode PWM controller designed for high efficiency, low cost “Point of Load” applications.

The hysteretic control scheme allows the use of ceramic output capacitors without the need for compensation components and difficult calculations.

Key Features

Miniature PWM Controller www.DataSheet4U.com for Buck Regulator POWER MANAGEMENT Description The SC2618 is a hysteretic mode PWM controller designed for high efficiency, low cost “Point of Load” applications. The hysteretic control scheme allows the use of ceramic output capacitors without the need for compensation components and difficult calculations. An internal soft start prevents output voltage from start up overshoot. A “Hiccup” short circuit protection provides protection against output short circuits as well as adverse input supply sequencing.
