Pulse-Width Dimming (MAX16825)

The MAX16825 provides three methods of pulsed-width

current dimming.

One method of pulse dimming the output channels is to

drive OE low while latching a different set of three bits

data. Holding OE low allows the output channels to fol-

low the state of the output latches. The duty cycle

depends on LE’s frequency. All output channels are

affected at the same time.
