UCC2580D-1 General Description

The UCC2580D-1, part of the UCC3580 family of PWM controllers, boasts advanced features for active clamp/reset and synchronous rectifier switching converter topologies. With a programmable deadtime between transitions, this controller optimizes efficiency by reducing voltage stresses on switches and minimizing switching losses. The inclusion of an auxiliary switch driver complements the main power switch, allowing for greater control and performance enhancements. Additionally, the active clamp/reset technique enables operation of single ended converters beyond 50% duty cycle, enhancing overall system flexibility and efficiency

Key Features

Self-Testing Diagnostic Feature for Immediate Fault Detection
Dynamic Frequency Scaling for Power Efficiency Optimization
Quad-Channel Real-Time Analog-to-Digital Conversion
Fully Integrated Microcontroller for Autonomous Operation
