The UC2843BD1 from ON Semiconductor is a fixed-frequency, current-mode controller designed for efficient off-line and DC-DC converter applications. It offers a cost-effective solution with minimal external components, featuring a trimmed oscillator for precise duty cycle control and a temperature-compensated reference.
Key electrical specifications include a wide operating voltage range from 7.6V to 30V, a maximum duty cycle of 96%, and an operating frequency of up to 500kHz. The device provides a transistor driver output and supports boost and flyback topologies. It also includes features like frequency control for precise operation.
This controller is housed in an 8-SOIC package, suitable for surface mount applications. The operating temperature range is -25°C to 85°C (TA). Its design incorporates protective features such as undervoltage lockout with hysteresis and cycle-by-cycle current limiting, making it a robust choice for power supply designs.
