Caution: Stresses beyond these values may destroy the device.
Source terminal of the internal Power MOSFET, typically clamped to common ground. VCC
Power supply input for the internal control circuits. Requires a bypass capacitor to smooth voltage spikes. Used for external synchronization or sensing current
Although the MOSFET is robust, an external RCD snubber across the primary winding is recommended to suppress high-voltage spikes caused by transformer leakage inductance. Common Fault Symptoms and Troubleshooting
