1. Always attach an outside heat sink when using the chip. Note that, the outside heat sink must be fastened onto a
2. Connect the cooling fin to GND potential.
3. Avoid short circuit to V
4. The temperature protection circuit will be actuated at T
5. The overvoltage protection circuit starts its operation at V
6. Take into consideration the heat radiation design particularly when V
