Notes:
(1) The DC/DC converter will operate at no load with reduced specifications.
(2) The maximum output current reduces the output power of the following devices to less than 10W:-
PT4225 =7.5W; PT4221 =5.4W; PT4226 =4.5W; PT4227 =3.9W.
(3) The Remote On/Off (pin 1) has an internal pull-up, and if it is left open circuit the converter will operate when input power is applied. The open-circuit
voltage is typically 5V. Refer to the application notes for interface considerations.
(4) See Safe Operating Area curves or contact the factory for the appropriate derating.
(5) An output capacitor is not required for proper operation.
(6) The case pins on through-hole pin configurations (N & A) must be soldered. For more information see the applicable package outline drawing.
