Fig.1 +VIN To increase the output voltage, an external resistor (Fig.1) or voltage source should be connected between the Trim and the common pin.

The voltage drop must not exceed 0.5V, although Trim and remote sense functions ons can be used in combination wit with each other, the maximum voltage increase is 0.5V. +VOUT VINN NNL10 When increasing the output voltage the maximum um output power of the NNL10 must not exceed the maximum output figures stated in the selection guide. SENSE LOAD Common Output Sequencing To simplify output sequencing, the NNL10 series offers an optional single wire interconnection that performs this function. Using this connection, up to four devices can be ‘daisy chained’ together, with the ‘DC OK’ signal from one converter signifying that the next converter can be enabled. A capacitor, simply connected to the daisy chain link, provides a settable delay in the sequence of the converters starting. Fig.3 #VT7PMUBHF 7065 7065 7*/ %$0, 513&4&5 7065 Typical capacitor values and corresponding delays are shown in the table below. 0/0'' 7065 7*/ Figure 3 shows a typical sequencing configuration, along with the voltage outputs that it produces. As well as reducing component count, making use of the ‘built-in’ sequencing capability means that only a single PCB track is required for a full sequencing solution. 7065 VIN 3.0VDC 5.5VDC Capacitor 0.22μF 0.22μF 0/0'' Delay 1.8ms 0.6ms 7065 7*/ %$0, 513&4&55$"1 7065 0/0'' 7*/ 7065 $BQBDJUPS RoHS COMPLIANCE INFORMATION This series is compatible with RoHS soldering systems with a peak reflow solder temperature of 245ºC.
