Texas Instruments DC DC Switching Controllers UCC3580D-31

The UCC3580D-31 is a PWM controller designed for various active clamp/reset and synchronous rectifier switching converter topologies. It features an auxiliary switch activation that complements the main power switch, with programmable deadtime for improved efficiency. The device operates with voltage mode control and includes feedforward operation, allowing for programmable limits on transformer volt-second product and PWM duty cycle. It provides high current gate drive capabilities for both main and auxiliary outputs, with a startup supply current of 100 ¬µA and operational current of 1.5 mA. The controller incorporates multiple protection features, including latched shutdown and soft restart, ensuring reliable operation under fault conditions. The UCC3580D-31 is specified for operation within a temperature range of 0¬8C to 70¬8C and is available in DIL-16 and SOIC-16 packages. Engineers may consider this product for applications requiring efficient power conversion with robust protection features and flexibility in design.
