Description
Description
The UC2843BN from STMicroelectronics is a high-performance current mode PWM controller designed for boost and flyback applications. It features a trimmed oscillator for precise frequency control, operating at 250 kHz, with current mode operation up to 500 kHz. The device includes automatic feed-forward compensation, latching PWM for cycle-by-cycle current limiting, and an internally trimmed reference with undervoltage lockout. It is suitable for driving N-Channel MOSFETs with a high current totem pole output.
