MAX1985 Description
The MAX1984/MAX1985/MAX1986 are white light-emitting diode (LED) drivers that use individual regulators to control the current of up to eight LEDs. A high-efficiency step-up regulator generates just enough voltage to keep all the current regulators in regulation. A versatile dimming interface acmodates analog, digitally adjusted pulse-width modulation (DPWM), or parallel control.
