MAX16815

19-4032; Rev 1; 7/09 KIT ATION EVALU E L B AVAILA www.DataSheet4U.com High-Voltage, 100mA/200mA Adjustable Linear High-Brightness LED Drivers with PWM Dimming General 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 highbrightness 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. ♦ 6.5V to 40V Operating Range ♦ Adjustable LED Current MAX16815: 35mA to 100mA MAX16828: 35mA to 200mA ♦ ±3.5% LED Current Accuracy ♦ High-Voltage DIM Input for Dimming Interface ♦ Integrated Pass Element with Low-Dropout Voltage (0.4V typ) ♦ 5V Regulated Output with 4mA Source Capability ♦ Thermal Shutdown ♦ Output Short-Circuit Protection ♦ Available in Small, Thermally Enhanced, 3mm x 3mm, 6-Pin TDFN and 8-Pin SO with Exposed Pad Packages ♦ -40°C to +125°C Operating Temperature Range Features MAX16815/MAX16828 Applications Automotive Interior: Map, Courtesy, and Cluster Lighting Automotive Exterior: Rear Combination...
