The UC3842BVDR2G 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.
This controller supports boost and flyback topologies and operates with a voltage input range of 10V to 30V. It is capable of current mode operation up to 500kHz, with the oscillator frequency guaranteed at 250 kHz. Key features include automatic feed-forward compensation, latching PWM for cycle-by-cycle current limiting, and a high-current totem pole output suitable for driving power MOSFETs.
Protective features include input and reference undervoltage lockouts with hysteresis, programmable output deadtime, and a latch for single-pulse metering. The UC3842BVDR2G is available in a 14-SOIC package, suitable for surface mounting. It is designed for applications requiring precise control and robust protection in power supply designs.
