Description
Description
The UC3843BD1 from onsemi is a high-performance current mode controller designed for boost and flyback DC-DC converter applications. It features a trimmed oscillator for precise frequency control, undervoltage lockout, and a high current totem pole output capable of driving power MOSFETs. The device operates at a guaranteed frequency of 250 kHz and supports cycle-by-cycle current limiting, making it suitable for isolated output step-up and step-down applications.
