MAX16831 Datasheet (Maxim Integrated Products)

MAX16831, High-Power LED Driver

The MAX16831 is a current-mode, high-brightness LED (HBLED) driver designed to control two external n-channel MOSFETs for the single-string LED current regulation.

The MAX16831 integrates all the building blocks necessary to implement fixed-frequency HBLED drivers with wide-range dimming control.
