The UCC2813QPWR-3Q1 from Texas Instruments is an automotive economy single-ended, 1MHz current mode PWM controller. This integrated circuit is designed for off-line and DC-to-DC fixed-frequency current-mode switching power supplies, requiring a minimal parts count.
Key electrical specifications include a supply voltage range of 3.6V to 12V, a maximum duty cycle of 99%, and a typical operating frequency of 1MHz. It features a 1.5% tolerance voltage reference and a fast 70ns response time from current-sense to gate-drive output. The device offers a 1A totem-pole output and operates with a low typical starting supply current of 100µA and an operating supply current of 500µA.
This controller supports multiple topologies including Boost, Flyback, and Forward converters. It is not a synchronous rectifier and does not feature clock synchronization, but it does include frequency control as a key feature. The output configuration is positive.
The UCC2813QPWR-3Q1 is supplied in an 8-TSSOP package suitable for surface mounting. It operates within a temperature range of -40°C to 125°C (TJ) and comes in a standard package quantity of 2,000 pieces on tape and reel.
