s Application s Precautions

1. External heatsink is needed when used. External heatsink should be fixed to the chassis.

2. Fin of the IC can be connected to GND.

3. Please prevent output to VCC short and output to GND short.

4. The temperature protection circuit will operate at Tj around 150 °C.

However, if temperature decrease, the protection circuit will automatically be decreased and resume
