UC3842BN Description

Short technical summary and product information.

The UC3842BN 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, operating at frequencies up to 500kHz. Key electrical specifications include an operating voltage range of 10V to 30V and a maximum duty cycle of 96%. It provides a transistor driver output and is capable of positive, isolation configurations.

 

The UC3842BN is housed in an 8-pin DIP package, suitable for through-hole mounting. It operates within a temperature range of 0°C to 70°C (TA). Protective features include undervoltage lockouts with hysteresis and cycle-by-cycle current limiting.

 

This device is well-suited for designers seeking a reliable and versatile current mode controller for power supply designs requiring high performance and minimal external component count.
