The UCC2580N-4 from Texas Instruments is a PWM controller designed for active clamp/reset and synchronous rectifier switching converter topologies. It features voltage mode control with feedforward operation and programmable limits for transformer volt-second product and PWM duty cycle. This device supports operation beyond 50% duty cycle, reducing voltage stresses on switches and allowing for greater flux swing in the power transformer.
Key electrical specifications include an operating voltage range of 8.5V to 15V and a maximum duty cycle of 66%. It incorporates control features like soft start. The UCC2580N-4 is suitable for Flyback and Forward topologies and provides isolated output.
Packaged in a 16-PDIP, the UCC2580N-4 is designed for through-hole mounting. Its operating temperature range is -55°C to 150°C (TJ). This controller is designed to implement high-performance pulse width modulation with an auxiliary switch driver and programmable deadtime.
