Notes:
(1) The DC/DC converter will operate at no load with reduced specifications.
(2) The Remote On/Off input has an internal pull-up. If it is left open circuit the module will operate when input power is applied. A low-leakage
(<100nA) MOSFET is recommended to control this input. The open-circuit voltage is less than 10V. See application notes for interface considerations.
(3) Output capacitor values are absolute. Allowances must be made for any additional de-coupling capacitors and the total external capacitor tolerance.
The value of external capacitance is limited due to regulator startup current requirements. Consult the factory for further details.
(4) For operation below 0°C, the required external output capacitor must have temperature stable characteristics. E.g. Tantalum or Oscon types.
(5) See Safe Operating Area curves or contact the factory for the appropriate thermal derating.
