Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
3. The device is not guaranteed to function outside operating range.
4. Specification for packaged product only.
5. The application is fully functional at low V DD (supply of the control section) if the external MOSFETs have enough low voltage V TH .
6. Measured in test mode.
7. The maximum duty-cycle is limited by the fixed mandatory off-time t OFF of typically 360ns.
