UC1825BJ Description

Short technical summary and product information.

The UC1825BJ from Unitrode is a switching controller designed for voltage mode operation. It is suitable for various DC-DC converter topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations.

 

This component operates within a voltage range of 8.4V to 30V and can handle a maximum duty cycle of 80%. The operating frequency is adjustable between 340kHz and 460kHz. It features control functions such as Current Limit, Enable, Frequency Control, Ramp, and Soft Start.

 

The UC1825BJ is designed for through-hole mounting and comes in a 16-CDIP package. It operates across a wide temperature range of -55°C to 125°C (TA). The device has 2 outputs and 1 output phase, with the output type specified as Transistor Driver and the output configuration as Positive. It also includes synchronous rectification and is not clock synchronized.

 

This controller is part of the DC DC Switching Controllers category, falling under Power Management ICs. Its specifications make it suitable for power supply designs requiring flexible and robust control.
