POWER MANAGEMENT Description
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 an expensive p-channel, 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 over-current protection, and an internally compensated error amplifier.
Pulse by pulse current limiting is implemented by sensing ...
