OVP
Output Overvoltage Protection. The OVP threshold is set at 1.36 V. Connect a resistive divider
from the OVP pin to the output and AGND2.

VDD2
Input Supply on the Secondary Side. Connect VDD2 to the output voltage of the power
supply for a self driven configuration. Connect a 4.7 µF capacitor from VDD2 to AGND2. The
size of this capacitor can be reduced if the input voltage to VDD2 is guaranteed to be stable.

VREG2
5 V Regulated LDO Output for Internal Bias and Powering of the Drivers of the Synchronous
Rectifiers. Do not use VREG2 as a reference or load. Connect a 1 µF capacitor from VREG2 to
AGND2.
