Notes:
(1) The input voltage Vin is applied and measured between ‘Data Line A’ (pin 10) and ‘Data Line B’ (pin 9), or between ‘Spare Line A’ (pin 8) and ‘Spare
Line B (pin 7). These inputs accept either polarity.
(2) The DC/DC converter will operate at no load with reduced specifications.
(3) The Output Inhibit (pin 13) is referenced to ‘Input Ref ’ (pin 4) and has an internal pull-up. If it is left open circuit the converter will operate when
input power is applied. The open-circuit voltage is typically 5 V. Refer to the application notes for interface considerations.
(4) An output capacitor is not required for proper operation.
(5) This is the default for a “Valid Device” PD detection signature.
(6) This is the default for a “Class 0” PD classification signature.
(7) See Safe Operating Area curves or contact the factory for the appropriate derating.
(8) During the reflow of the SMD package version do not elevate the peak temperature of the module, pins, or internal components above the stated maximum.
