Texas Instruments UCC3580-3 Single-Ended Active Clamp/Reset PWM UCC3580N-3

The UCC3580-3 is a single-ended active clamp/reset PWM controller designed for high-performance pulse width modulation applications. It features an auxiliary switch activation that complements the main power switch drive, allowing for programmable deadtime between switch activations. This device operates with voltage mode control and includes feedforward operation, which enhances performance by adjusting the PWM duty cycle based on input voltage variations. The UCC3580-3 supports high current gate driving capabilities for both main and auxiliary outputs, with a maximum output current of 1.2A for OUT1 and 0.4A for OUT2. It incorporates multiple protection features, including latched shutdown and soft restart, ensuring reliable operation under fault conditions. The device operates with a low supply current of 1.5 mA during normal operation and 100 ¬µA during startup. This PWM controller 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 is suitable for applications requiring efficient power conversion with reduced voltage stresses and switching losses.
