Hysteresis
1. The module has an adaptable extended Turn-On Delay interval, Tdelay, of 25mS. The extended Tdelay will occur when the module restarts following
either: 1) the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout (which causes module shutdown), and then back
to normal; or 2) toggling the on/off signal from on to off and back to on without removing the input voltage. The normal Turn-On Delay interval, Tdelay
will occur whenever a module restarts with input voltage removed from the module for the preceding 1 second.
