Simple, Synchronous Voltage Mode PWM Controller

The SC1104A SC1104B is a versatile voltage-mode PWM con- troller designed for use in single ended DC/DC power supply applications. A simple, fixed frequency high effi- ciency buck Regulator CAN be implemented using the SC1104A SC1104B 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. SC1104A SC1104B features include temperature compensated Voltage Reference triangle wave Oscillator current limit Comparator and an externally compensated error ampli- fier. Current limit is implemented by sensing the voltage drop across the top FETs RDS(ON) . The SC1104 operates at fixed frequencies of 300kHz(A) or 600kHz(B) providing an optimum com- promise between efficiency, external component size, and cost. 600kHz switching frequency is reserved for the SC1104B +5VCC operation only.
