LGATE

Connect LGATE to the lower MOSFET gate. This pin provides the gate drive for the

lower MOSFET.

18

VCC

Provide a 12V bias supply for the chip to this pin.

19

OVP

The OVP pin can be used to drive an external SCR in the event of an overvoltage

condition.

20

RT

This pin provides oscillator switching frequency adjustment. By placing a resistor

according to the following equation:

Conversely, connecting a pull-up resistor (RT) from this pin to VCC reduces the

switching frequency according to the following equation:
