Dynamic Headroom Control (DHC) with an optional external PMOS FET to minimize IC thermal stress when the supply voltage exceeds the LED string forward voltage. It include.

requiring dimming without use of the EN pin. For added system reliability, the IS32LT3124 integrates fault detection cir.

The IS32LT3124 is a linear programmable current regulator consisting of 4 output channels capable of up to 150mA each. Individual external resistors set the maximum current level for each channel. The outputs can be combined to provide a higher curre.
