UCC3804D Description

Short technical summary and product information.

The Texas Instruments UCC3804D is a high-speed, low-power integrated circuit that contains the necessary control and drive components for off-line and DC-to-DC fixed frequency current-mode switching mode power supplies. It features a 1MHz operation frequency, a typical starting supply current of 100µA, and an operating supply current of 500µA. The device supports topologies including Boost, Buck, Flyback, and Forward.

 

Key features include internal soft start, internal fault soft start, and internal leading-edge blanking of the current-sense signal. It provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate drive output. The voltage reference has a 1.5% tolerance. The UCC3804D operates with a supply voltage range of 8.3V to 12V and has a duty cycle of 49%.

 

This component is housed in an 8-SOIC package and is designed for surface mount applications. The operating temperature range is specified from 0°C to 70°C. Its design is similar in pin configuration to the UCx84x family, offering added features for efficient power supply design.
