The UC3843BD1G from ON Semiconductor is a fixed-frequency, current-mode controller optimized for 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 an operating voltage range of 7.6V to 30V and the ability to operate at frequencies up to 500kHz. The controller supports Boost and Flyback topologies and provides a transistor driver output. It also includes features like automatic feed-forward compensation and latching PWM for cycle-by-cycle current limiting.
This device is housed in an 8-SOIC package, suitable for surface mounting. It operates within a temperature range of 0°C to 70°C (TA). The UC3843BD1G is designed for applications requiring efficient power conversion with robust control features.
