... Description The AUIR2085S is a self oscillating half-bridge driver IC with 50% duty cycle ideally suited for 36V – 75V half-bridge DC-bus converters. This product is also suitable for push-pull converters without restriction on input voltage. Each channel frequency is equal to f Dead-time can be controlled through proper selection of C Internal soft-start increases the pulse width during power up and maintains pulse width matching for the high and low outputs throughout the start up cycle ...
