Description

1

GND

P

Chip reference ground

2

ROVP

I

Connect a resistor to ground to adjust the output overvoltage protection. It is

recommended to use a resistor greater than 6K to connect to GND. When the pin is left

floating, there is no OVP protection function. The ROVP pin also integrates an enable

function, which shuts down the system when this pin is grounded.
