SC1103 Datasheet (Semtech Corporation) - Asynchronous Voltage Mode PWM Controller

SC1103, Asynchronous Voltage Mode PWM Controller

The SC1103 is a versatile, low-cost, voltage-mode PWM controller designed for 12V input DC/DC power supply applications.

A simple, fixed-voltage buck regulator can be implemented using the SC1103 with a minimum of external components.

Internal level shift and drive circuitry eliminates the need for

SC1103 Features

* include a temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift over-current protection, and an internally compensated error amplifier. Pulse by pulse current limiting is implemented by sensing the differential voltage across an external resis
