Description
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.
