UC3842BD1G Description

Short technical summary and product information.

The UC3842BD1G from ON Semiconductor is a high-performance, fixed-frequency current mode controller. It is engineered for Off-Line and DC-DC converter applications, providing a cost-effective solution with minimal external components.

 

Key electrical specifications include an operating voltage range of 10V to 30V and a frequency capability of up to 500kHz. The controller features a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, a high-gain error amplifier, and a current sensing comparator. Protective features include undervoltage lockouts with hysteresis, cycle-by-cycle current limiting, and programmable output deadtime.

 

This device is housed in an 8-SOIC surface mount package. The UC3842BD1G is suitable for applications requiring efficient power conversion and robust control, such as boost and flyback topologies. It is designed for ease of use, requiring minimal external components for operation.

 

The controller operates within a temperature range of 0°C to 70°C (TA). It is also noted as being Pb-Free and Halide-Free.
