Usage Notes
1) Depending on the maximum application output power, external heatsink may be needed.
External heatsink should be fixed to the chassis.
2) Fin of the IC can be connected to GND.
3) Please prevent output to V
CC
short and output to GND short.
4) The temperature protection circuit will operate at T
j
around 150
°C.
However, if the temperature decreases, the
protection circuit would automatically be deactivated and resume normal operation.
