Краткое описание:
Quad Channel Linear LED Driver with Dynamic Headroom Control (DHC)
Дополнительная информация
The IS32LT3124 is a linear programmable current regulator consisting of 4 output channels capable of up to 150mA each. It features 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. The device includes two modes for output power: Shunt Regulator and Series Regulator. It integrates fault detection for open/short circuits and over-temperature conditions, and is available in six versions (A through F) to support different fault reporting and PWM dimming requirements.
