NCR420PAS / NCR421PAS
150 mA LED driver in DFN2020D-6
To savely drive currents that are above the limits of the NCR42xPAS, two or more devices can
be parallel connected as illustrated in Figure 28. When choosing the same values for the external
resistors, the drive current splits equally and the capability of handling excess power is doubled.
Both, NCR420PAS and NCR421PAS can be used in this configuration.
