... NCP4561 can be calculated from the following formula: Ptot + gnd or Vin max + output current is needed, the ground current is extracted from the data−sheet curves: 4 mA. For a NCP4561SN28T1 (2.8 V) delivering 80 mA and operating at 25°C, the maximum input voltage will then be 8.3 V. http://onsemi.com Jmax A R ...
