PWRGD Output Configuration,
Opto-isolated Enable
Some applications require opto-isolator interface to the Enable pin of the DC/DC converter. Make sure that the current transfer
ratio of the opto-coupler selected is at least 100% to ensure proper pull-down current on the Enable pin.

Notes:
1. Under Voltage Shutdown (UV) set to 37V.
2. Over Voltage Shutdown (OV) to 57.8V.
3. Other power good outputs will have the same
configuration as PWGRGD-A for Active High Enabled
Converters.
