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 Low Enabled

Converters.

V EE

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.
