DESCRIPTION
MAS1634 is a quad LED driver IC. It has four
constant current sink type outputs for driving up to
four LEDs. It has wide supply voltage range and low
power consumption ideally suitable for low power
applications. MAS1634 can be set into power down
mode by a power down control pin. The LED driver
control inputs have pull down resistors and which are
disabled in the power down mode.
