gures stated in the selection guide. 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. typical capacitor values and corresponding delays are shown in the table below. figure 3 shows a typical sequencing con? guration, 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. v in capacitor delay 3.0v dc 0.22f 1.8ms 5.5v dc 0.22f 0.6ms v in +v out common load sense nnl10 # v t 7 p m u b h f $ b q b d j u p s 7 * / 7 * / 0 / 0 ' ' 7 * / 0 / 0 ' ' 7 * / 0 / 0 ' ' 7 0 6 5 7 0 6 5 7 0 6 5 7 0 6 5 7 0 6 5 7 0 6 5 7 0 6 5 7 0 6 5 5 1 3 & 4 & 5 5 1 3 & 4 & 5 5 $ " 1 % $ 0 , % $ 0 , fig.3 rohs compliance information this series is compatible with rohs soldering systems with a peak re?
