MAX1986 - Ultra-High-Efficiency White LED Drivers

Download the MAX1986 datasheet PDF (MAX1984 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for ultra-high-efficiency white led drivers.

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.

19-2761; Rev 0; 1/03 EVAALVUAAILTAIOBNLEKIT Ultra-High-Efficiency White LED Drivers MAX1984/MAX1985/MAX1986 General 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 accommodates analog, digitally adjusted pulse-width modulation (DPWM), or parallel control. The individual current regulators allow good current matching between LEDs. Open or shorted LEDs cannot affect the performance of other LEDs. The step-up regulator achieves high efficiency by using synchronous rectification.
