150 mA LED driver in DFN2020D-6
9. Application information
Figure 26 shows a typical application circuit for an LED driver. The constant current ensures a
constant brightness in all LEDs. The output current can be adjusted between 10 mA and 150 mA
by connecting resistor Rext. Figures 7 and 17 give a first indication for choosing the external resitor
Rext. The minimum input voltage is given by voltage drop at the LED's VLED and the maximum is
governed by the maximum power dissipation
VLED + Vout, min < VCC < Ptot /Iout + VLED

Fig. 26. LED driver application diagram
NCR421PAS can be used for PWM dimming or on/off function by driving the VEN pin. The
enable voltage depends on the drive current, see Figure 23. Figure 27 shows a typical application
where VEN is driven via a micro directly. To control more than one NCR421PAS devices by one
microcontroller output, a shift register (for example 74AHC(T)594PW) can be used.

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.
