The UCC2813-1 device family from Texas Instruments offers high-speed, low-power integrated circuits for off-line and DC-to-DC fixed-frequency current-mode switching power supplies. This specific part, the UCC2813DTR-1, is designed for economy and low power consumption, utilizing BiCMOS technology.
Key electrical specifications include an operating frequency of up to 1MHz, a maximum duty cycle of 49%, and a supply voltage range of 7.4V to 12V. It features a typical starting supply current of 100μA and an operating supply current of 500μA. The device also includes internal features such as soft start and leading-edge blanking of the current-sense signal, along with a 1.5% tolerance voltage reference.
The UCC2813DTR-1 is housed in an 8-SOIC package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The part offers a 1A totem-pole output with a typical response time of 70ns from current-sense to gate-drive output.
This controller is designed for minimal parts count in switching power supply designs. Its pin configuration is similar to the UC384x device family, providing a familiar interface for designers.
