The UCC3813PWTR-0 from Texas Instruments is a high-speed, low-power integrated circuit that provides the control and drive components for fixed-frequency current-mode switching power supplies. It is suitable for off-line and DC-to-DC applications, offering a minimal parts count.
Key electrical specifications include an operating voltage range of 6.9V to 12V, a maximum duty cycle of 99%, and a switching frequency of 46kHz. The device features adjustable switching frequency, current limiting, dead time control, an error amplifier, fixed frequency operation, leading-edge blanking, multi-topology support, and soft start.
This controller is available in an 8-TSSOP package, designed for surface mount applications. It operates within a temperature range of 0°C to 70°C (TA). The UCC3813-x family offers features like internal full-cycle soft start and internal leading-edge blanking of the current-sense input, simplifying design and improving performance.
With a typical starting supply current of 100µA and operating current of 500µA, it is designed for economy and low power consumption. The device also boasts a fast response time from current-sense to gate-drive output of 70ns and a 1.5% tolerance voltage reference.
