1 To order with optional control pin insert an ‘E’ prior to the suffix C, i.e. NCM6S1205EC.
2 Calculated using MIL-HDBK-217F FN2, parts stress method with nominal input voltage at full load.
3. 5V inputs have a 2:1 input range.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
