The UC3843BVDR2G from On Semiconductor is a high-performance, fixed-frequency current mode controller engineered 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.
This integrated circuit boasts a high gain error amplifier, a current sensing comparator, and a high current totem pole output, making it ideal for driving power MOSFETs. Protective features include input and reference undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. The device supports a voltage range of 7.6V to 30V and operates at frequencies up to 500kHz.
Available in a 14-SOIC package, the UC3843BVDR2G is designed for surface mounting. Its topology supports Boost and Flyback configurations, functioning as a Step-Up or Step-Up/Step-Down converter. The controller features frequency control for precise operation and is suitable for applications requiring positive, isolation-capable outputs.
