IR2086S

The IR2086S(PbF) is a self oscillating full-bridge controller and driver IC with 50% duty cycle ideally suited for 36V-75V full-bridge DC Bus Converters. Dead time can be controlled through proper selection of CT and can range from 50 to 200nsec. Internal soft start increases pulse width on power up and maintains equal pulse widths for the high and low outputs throughout the start up cycle. Undervoltage lockout prevents operation if Vcc is less than 7.5 Vdc. Over current shutdown occurs when the voltage on the Cs pin exceeds 200mV. Restart after overcurrent trip can be delayed by adjusting the external capacitor. The delay time ranges from 10µs to 1s.
