The UC3842BD1R2 is a fixed-frequency current mode controller from ON Semiconductor, suitable for off-line and DC-DC converter applications. It offers a cost-effective solution with minimal external components.
Key features include a trimmed oscillator for precise frequency control, a temperature-compensated reference, a high-gain error amplifier, and a current sensing comparator. The output stage is a high-current totem pole output, ideal for driving power MOSFETs. Protective features include undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and programmable output deadtime.
This controller supports boost and flyback topologies and operates at frequencies up to 500kHz. It is available in an 8-SOIC package, designed for surface mounting.
Applications include various DC-DC converters where precise control and protection are required.
