SC2618 Miniature PWM Controller for Buck Regulator

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 outpu.
