16-Output PWM LED Drivers

for Message Boards

Multiplexed vs. Nonmultiplexed Operation

The MAX6972/MAX6973 can double the number of

LEDs driven from 16 to 32 through multiplexing. When

multiplexing, the two outputs, MUX0 and MUX1, drive

two external pnp transistors, such as FMMTL717, used

as common-anode power switches (see Figure 5).
