200V Dual Smart Secondary Side High Speed SR Controller in a 8-Lead SOIC Package. Used to drive two N-Channel power MOSFETs used as Synchronous Rectifiers in resonant converter applications.; Standard pack quantity of the IR1168
The maximum operating temperature range for the IR1168SPBF is -40°C to 150°C, with a junction temperature of up to 175°C.
Proper cooling can be achieved by using a heat sink with a thermal resistance of less than 10°C/W, and ensuring good airflow around the device. Additionally, the PCB layout should be designed to minimize thermal resistance and ensure good heat dissipation.
The recommended gate drive voltage for the IR1168SPBF is between 10V and 15V, with a maximum voltage of 20V. A higher gate drive voltage can improve switching performance, but may also increase power consumption.
Overvoltage protection can be achieved by using a voltage clamp or a zener diode to limit the voltage across the device. Overcurrent protection can be achieved by using a current sense resistor and a comparator to detect overcurrent conditions, and then shutting down the device or reducing the current limit.
The recommended layout and routing for the IR1168SPBF involves keeping the high-frequency switching nodes (e.g. drain and source) as close as possible to the device, and using a solid ground plane to reduce electromagnetic interference (EMI). Additionally, the gate drive circuitry should be kept separate from the power circuitry to minimize noise coupling.
