UCC25705DGKTR Description

Short technical summary and product information.

The Texas Instruments UCC25705DGKTR is an 8-pin voltage mode primary side controller designed for high-performance isolated and non-isolated power converters. It features a high-speed oscillator with integrated feed-forward compensation for improved performance and a fast 25 ns current limit delay for quick response to overload conditions.

 

This controller operates with an input voltage range of 8.2V to 15V and supports a maximum duty cycle of 93%. It includes features such as a programmable maximum duty cycle clamp and an optocoupler interface. The device is suitable for applications requiring operation above 4 MHz and has a low start-up current of 50 μA and an operating current of 4.2 mA at 1 MHz.

 

The UCC25705DGKTR is available in an 8-VSSOP package, known for its small footprint which minimizes board area and height. It is also offered in 8-pin SOIC (D) and PDIP (P) packages. The operating temperature range is -40°C to 85°C (TA).
