The UCC3580N-1 is a PWM controller designed for various active clamp/reset and synchronous rectifier switching converter topologies. It features an auxiliary switch driver that complements the main power switch, allowing for programmable deadtime between transitions. This controller supports voltage mode control with feedforward operation and includes programmable limits for transformer volt-second product and PWM duty cycle. The device operates with a low supply current of 100 ¬µA during startup and 1.5 mA in operation. It provides high current gate drive outputs for both main and auxiliary switches, with output currents ranging from 0.6 A to 1.2 A for OUT1 and up to 0.4 A for OUT2. The UCC3580N-1 is specified for operation within a temperature range of 0¬8C to 70¬8C and is available in 16-pin DIL and SOIC packages. It includes multiple protection features such as latched shutdown and soft restart, making it suitable for robust applications.
