UCC2801D Description

Short technical summary and product information.

The UCC2801D from Texas Instruments is a low-power BiCMOS current-mode PWM controller. It is suitable for off-line and DC-to-DC fixed frequency switching mode power supplies.

 

This controller operates with a voltage range of 7.4V to 12V and has a maximum duty cycle of 49%. Key electrical features include frequency control, a typical operating frequency of 46kHz, and a typical starting supply current of 100μA, with an operating current of 500μA. The device offers a typical response time of 70ns from current-sense to gate drive output and a 1.5% tolerance voltage reference.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface mount package, the UCC2801D operates within a temperature range of -40°C to 85°C (TA). It supports multiple topologies including Boost, Flyback, and Forward Converter configurations. The output type is a Transistor Driver, with a single positive output phase.

 

This component is designed for applications requiring efficient power conversion. Its features like internal soft start and leading-edge blanking (mentioned in fetched text) contribute to stable operation.
