Description

The SC1103 is a versatile, low-cost, voltagemode PWM controller designed for use in single ended 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 an expensive pchannel, high-side switch. The small device footprint allows for compact circuit design.

SC1103 features include a temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift overcurrent 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 SC1103 operates at a fixed frequency of 200kHz, providing an optimum compromise between efficiency, external component size, and cost.
