The UCC2813QDR-2Q1 from Texas Instruments is a high-speed, low-power integrated circuit designed for fixed-frequency current-mode switching power supplies. It offers a minimal parts count and features internal soft start and leading-edge blanking of the current-sense signal.
This controller operates at up to 1MHz with a 100% maximum duty cycle. Key electrical specifications include a 12.5V turn-on threshold and an 8.3V turn-off threshold for undervoltage lockout (UVLO), a 1.5% tolerance voltage reference, and a 1A totem-pole output. It also provides a typical response time of 70ns from current-sense to gate drive output.
Qualified for automotive applications, the UCC2813-2-Q1 is specified for the temperature range of -40°C to 125°C. It features ESD protection exceeding 200V using the machine model. The device is available in an 8-SOIC package suitable for surface mounting.
This controller is ideal for off-line power supplies due to its higher reference and UVLO hysteresis. It integrates essential control and drive components, simplifying the design of efficient power conversion systems.
