UCC2802D Description

Short technical summary and product information.

The Texas Instruments UCC2802D is an obsolete, high-speed, low-power BiCMOS current-mode PWM controller designed for off-line and DC-to-DC switching mode power supplies. It integrates essential control and drive components, minimizing external part count.

 

Key electrical specifications include an operating supply voltage range of 8.3V to 12V and a frequency of up to 1MHz. The device features a 99% maximum duty cycle and current limiting fault protection. It operates within a temperature range of -40°C to 85°C.

 

This controller offers internal features such as soft start and leading-edge blanking of the current-sense signal. It has a typical operating supply current of 500μA and a typical starting supply current of 100μA. The output stage provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate drive.

 

The UCC2802D is available in an 8-SOIC package, suitable for surface mounting. It is supplied in tubes with a standard quantity of 75 units or in large tape and reel with 2500 units.
