DESCRIPTION
· The UCC3580 family of PWM controllers is designed for active clamp/reset and synchronous rectifier switching converter topologies.
· It includes an auxiliary switch driver complementary to the main power switch with programmable deadtime.
· The active clamp/reset technique allows single-ended converters to operate beyond 50% duty cycle, reducing voltage stresses and switching losses.
· The oscillator is programmed with resistors and a capacitor to set switching frequency and maximum duty cycle.
FEATURES
· Provides auxiliary switch activation complementary to the main power switch drive.
· Programmable deadtime (turn-on delay) between activation of each switch.
· Voltage mode control with feedforward operation.
· Programmable limits for transformer volt-second product and PWM duty cycle.
· High current gate driver for both main and auxiliary outputs.
· Multiple protection features with latched shutdown and soft restart.
· Low supply current (100 µA startup, 1.5 mA operation).
APPLICATIONS
· Suitable for implementing active clamp/reset and synchronous rectifier switching converter topologies.
· Ideal for fixed frequency, high-performance pulse width modulation applications.
· Used in single-ended converters requiring operation beyond 50% duty cycle.
· Effective in reducing voltage stresses and switching losses in power converters.
