Description
Description
The UC3843BD1 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 undervoltage lockout, cycle-by-cycle current limiting, and a high current totem pole output stage suitable for driving N-Channel MOSFETs. It operates with a supply voltage of up to 30 V and offers low start-up and operating current.
