SC2603

Simple PWM Boost Controller

POWER MANAGEMENT

Description

The SC2603 is a versatile, low-cost, voltage-mode PWM

controller designed for 16V input DC/DC power supply

applications. A simple, fixed-voltage boost regulator can

be implemented using the SC2603 with a minimum of

external components. The small device footprint

allows for compact circuit design.

SC2603 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 resistor, or an

appropriately sized PC board trace.

The SC2603 operates at a fixed frequency of 200kHz,

providing an optimum compromise between efficiency,

external component size, and cost.

Features
