UCC1580-1,-2,-3,-4 UCC2580-1,-2,-3,-4 UCC3580-1,-2,-3,-4 SLUS292D is a series of high-performance pulse width modulation controllers from TI, which have a variety of features, including auxiliary switch activation function, programmable dead time (turn-on delay), voltage mode control and feedforward operation, programmable limits for both transformer voltage-second product and PWM duty cycle, high current gate driver for both main and auxiliary outputs, multiple protection features, with latched shutdown and soft restart low supply current (100 mA startup, 1.5 mA operation).
The UCC1580, UCC2580, and UCC3580 families are single‑ended active‑clamp/reset PWM controllers with an auxiliary switch driver. They support programmable dead‑time, voltage‑mode control with feed‑forward, and multiple protection features such as latched shutdown and soft restart.
The document lists electrical specifications (e.g., oscillator frequency 370‑430 kHz, maximum duty cycle 63‑69 %), pin functions, mechanical dimensions for the 16‑pin DIL/SOIC packages, and application information such as output driver current capabilities (OUT1 up to 0.5 A source/1 A sink, OUT2 up to 0.3 A) and temperature ranges for each device variant.
