SC1103
SC1103 is Asynchronous Voltage Mode PWM Controller manufactured by SEMTECH.
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 ponents. Internal level shift and drive circuitry eliminates the need for an expensive p-channel, high-side switch. The small device footprint allows for pact circuit design.
SC1103 Features include a temperature pensated voltage reference, triangle wave oscillator, current limit parator, frequency shift over-current protection, and an internally pensated error amplifier. Pulse by pulse current limiting is implemented by...
