6. The function of “PT”:
This signal is prepared for extra OVP/OPP (VPT > 1.25V) or another Disable Under Voltage
Protection function (VPT < 0.62V)
7. Reference Application Ciruit:
8. In some application power system, adding an external resistor (R9) could reduce the peak value
spike from the environments to pin 9 (REM) and avoid pin 9 (REM ) damaged by the external noise.
