The 1 MHz switching ceiling lets the designer shrink the magnetics and output capacitors compared to a 100 kHz part, though the 49% maximum duty cycle limits the step-down ratio in a forward converter to roughly half the input. Start-up threshold is 11.3 V, with the Vcc operating range from 8.3 V to 11 V — the bias rail must stay above 8.3 V under load to keep the controller running. The internal switch is not integrated; an external MOSFET handles the power stage. Control features include frequency control and sync, which allows multiple converters to share a common clock and avoid beat-frequency ripple on the output bus. ## Package, temperature grade, and sourcing posture Housed in a 16-SOIC wide-body (7.50 mm width) package, surface-mount. Sourced to order against the BOM line.","metaTitle":"UCC3810DWTR TI offline PWM controller, 1 MHz, 16-SOIC","metaDescription":"Texas Instruments UCC3810DWTR offline PWM controller, multi-topology, 1 MHz switching, 16-SOIC.
