Notes:
(1) The DC/DC converter will operate at no load with reduced specifications.
(2) The Remote On/Off (pin 1) has an internal pull-up, and if it is left open circuit the module will operate when input power is applied. Refer to the
application notes for interface considerations.
(3) See Safe Operating Area curves or contact the factory for the appropriate derating.
