Product introduction

The UC1824's PWM control unit series is best suited for high frequency switching power supply applications. Special attention is given to minimizing the propagation delay of the amplifier logic circuit by comparing and maximizing the bandwidth and slew rate of the error. The controller is designed for both modes or voltage mode systems with the current input voltage feedforward function.

The protection circuit includes a threshold current limit comparator with 1 - V, a TTL-compatible shutdown port, and a soft-start pin to clamp doubles for maximum duty cycle. The logic where full locking provides free operation of jitter, prohibiting multiple pulses at the output. The hysteresis of the mV section with 800 undervoltage lockout guarantees low start-up current.
