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.
