Power OFF
At power OFF, the input voltage of the transformer gradually decreases and then V
IN
of IC also decreases
according to the input voltage. When V
IN
becomes lower than 10 V*
2
or Vref becomes lower than 4.7 V,
UVL1 (UVL2) operates again and the PWM pulse stops.
Note: 2. The value is for the HA17384S/H.
The value is 7.6 V for the HA17385H.
