The voltage drop must not exceed 0.5V, although Trim and remote sense functions can be used in combination with each other, the maximum voltage increase is 0.5V. +VOUT VIN NNL10 When increasing the output voltage the maximum output power ower of the NNL10 must not exceed the maximum output figures stated in the selection lection guide.

Using this con connection, up to four devices es can be ‘daisy chained’ together, geth with th the ‘DC OK’ signal from one converter signifying ng that t the he next converter can c be enabled. A capacitor, simply connected to the daisy chain link, provides a settablee delay in the sequence of the converters starting.
