MAX16828

High-Voltage, 100mA/200mA Adjustable Linear High-Brightness LED Drivers with PWM Dimming

High-Voltage LED Drivers with Adjustable LED Current and High-Voltage Dimming Input Ease Driver Design


Please check latest availability status for a specific part variant.

Description

The MAX16815/MAX16828 current regulators operate from a 6.5V to 40V input voltage range and deliver up to 100mA (MAX16815) or 200mA (MAX16828) to high-brightness LED (HB LED) loads. The output current is adjusted by using an external current sense resistor in series with the LEDs. The MAX16815/MAX16828's dimming input allows wide-range "pulsed" PWM operation. An on-board pass element minimizes external components while providing ±3.5% output-current accuracy.

The MAX16815/MAX16828 are available in a thermally enhanced, 3mm x 3mm, 6-pin TDFN package with exposed pad and in an 8-pin SO package with exposed pad; they are specified over the automotive -40°C to +125°C temperature range.
