Description
The IR2085S 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 OSC, which can be set by selecting R T & C T, where f OSC = 1/(2*R T .C T ).
Dead-time can be controlled through proper selection of C T 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 V CC is less than 7.5V.
