UC3825BDW Description

Short technical summary and product information.

The UC3825BDW from Texas Instruments is a versatile PWM controller suitable for various offline switching power supply designs, including Boost, Buck, Flyback, and Forward topologies. It operates at switching frequencies up to 1 MHz, offering efficient power conversion.

 

Key electrical features include a wide operating voltage range of 10V to 22V and a maximum duty cycle of 50%. The controller incorporates essential features like frequency control, soft start, and current limiting for robust operation. It also provides a 2A peak output current capability and a low 100μA startup current, making it ideal for off-line applications.

 

This device is available in a 16-SOIC surface mount package, facilitating integration into compact electronic designs. The operating temperature range is -55°C to 150°C (TJ), ensuring reliability in demanding environments.

 

The UC3825BDW is an improved version of older PWM controllers, offering enhanced performance characteristics such as a 50ns propagation delay to the output and a high-speed overcurrent comparator.
