MAX16838
Integrated, 2-Channel, High-Brightness LED Driver with High-Voltage Boost and SEPIC Controller
General Description
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 directly withstands automotive load-dump events.
For a 5V Q10% input voltage, connect VIN to VCC.
The wide input range allows powering HB LEDs for small-to-medium-sized LCD displays in automotive and display backlight applications.
