To increase the output voltage, an external resistor (Fig.1) or voltage source should be connected between the Trim and the common pin. RTRIM-UP = 24.080 - RINTERNAL KΩ ΔVOUT VTRIM-UP = 0.8- ΔVOUT X RINTERNAL 30.100 ΔVOUT is the required change in output voltage in V. To decrease the output voltage, an external resistor (Fig. 2) or voltage source should be connected between the Trim pin and the +VOUT pin. RTRIM-DOWN = ΔVOUT-0.8 -1 x 30.100 -RINTERNAL KΩ ΔVOUT VTRIM-DOWN = 0.8+ ΔVOUT X RINTERNAL 30.100 The trim pin should be left disconnected if not used.

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. When increasing the output voltage the maximum output power of the NNL10 must not exceed ower the maximum output figures stated in the selection guide. lection VIN +VOUT Output Sequencing ing To simplify output sequencing, the NNL10 series offers seq offer an optional single wire interconnection that performs this t perform function. Using this connection, up to four devices can con es be ‘daisy chained’ together, with the ‘DC OK’ signal from geth th one converter signifying that the next converter can be ng t he c enabled. A capacitor, simply connected to the daisy chain link, provides a settable delay in the sequence of the e converters starting. Typical capacitor values and corresponding delays are shown in the table below. for rep us ontact C ENDED COMM GNS E NOT R W DESI model E nt FOR N aceme l Fi Fig.3 NNL10 SENSE LOAD Common 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.
