The IR2085S is a self-oscillating half-bridge driver IC with 50% duty cycle ideally suited for 36V – 75V halfbridge DC-bus converters. This product is also suitable for push-pull converters without restriction on input voltage. Each channel frequency is equal to fOSC, which can be set by selecting RT & CT, where fOSC = 1/(2*RT.CT). Dead-time can be controlled through proper selection of CT and can range from 50ns to 200ns. 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. The IR2085S initiates a soft start at power up and after every overcurrent condition. Undervoltage lockout prevents operation if VCC is less than 7.5V.
