MAX16838, High-Brightness LED Driver

The MAX16838 is a dual-channel LED driver that integrates both the DC-DC switching boost regulator and two 150mA current sinks.

A current-mode switching DC-DC controller provides the necessary voltage to both strings of HB LEDs.

The MAX16838 accepts a wide 4.75V to 40V input voltage range and direct

MAX16838 Features

* an adaptive output-voltage adjustment scheme that minimizes the power dissipation in the LED current sink paths. The MAX16838 can be combined with the MAX15054 to achieve a buck-boost LED driver with two integrated current sinks. The channel current is adjustable from 20mA to 150mA using an external
