NOTES:
1. Measure from high line to low line.
2. Single: from full load to 1/4 load.
Dual: load balanced from full load to 1/2 load.
3. Measure with 1uF ceramic cap. connected to the output pins.
4. Defined as case temperature and 3~5°C recovery
hysteresis; Non-latching shutdown protection.
5. This converter can operating at no load condition but
10% loading on the output is preferred to maintain
specified regulation operation. under no load conditions
will not damage these devices,. However they may not
meet all listed specification.
6. Standard product is active high, active low remote On/Off
option is available, to order suffix a “N” to the model
number e.g.: UM6723V3SN.
