The IR2086S is a self oscillating full-bridge controller and driver IC with 50% duty cycle ideally suited for 36V-75V full-bridge DC Bus Converters.
The document describes the IR2086S as a high-speed, 100V, self-oscillating full-bridge driver designed to enable DC-Bus Converters for 36V-75V applications with reduced component count. Key features include adjustable dead time (50nsec ~ 200nsec), overcurrent protection with an adjustable hiccup period, and undervoltage lockout.
| Operating Frequency | Up to 500KHz per channel |
|---|---|
| Output Current | +/-1.2A |
| Dead Time Range | 50 to 200nsec |
| Undervoltage Lockout Threshold | 7.5 Vdc (Min) |
| Overcurrent Shutdown Threshold | 200mV on Cs pin |
| Package Type | 16-Lead SOIC |
Frequency is set using a resistor between Vcc and CT, and a capacitor from CT to GND.
The device supports a maximum output frequency of 500 kHz per channel.
Lowering the value of the timing capacitor results in shorter dead time between outputs.
