High-Voltage, 100mA/200mA Adjustable Linear High-Brightness LED Drivers with PWM Dimming
General DescriptionThe 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 opera-
tion. An on-board pass element minimizes external com-
ponents 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.

Electrical CharacteristicsStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Absolute Maximum Ratings
Note 2: All devices are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by
design.
Note 3: Resistors were added from OUT to CS+ to aid with power dissipation.
Note 4: Dropout is measured as follows:Connect RO from OUT to CS+. Connect RSENSE = 2Ω (MAX16815) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set VIN = 12V (record VOUT1 = VOUT). For VIN = 40V, use RO = 360Ω; for VIN = 6.5V, use RO = 56Ω.Reduce VIN until VOUT = 0.97 x VOUT1 (record as VIN2 and VOUT2). DVDO = VIN2 - VOUT2.
Note 5: Dropout is measured as follows:Connect RO from OUT to CS+. Connect RSENSE = 1Ω (MAX16828) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set VIN = 12V (record VOUT1 = VOUT). For VIN = 40V, use RO = 180Ω; for VIN = 6.5V, use RO = 27Ω.Reduce VIN until VOUT = 0.97 x VOUT1 (record as VIN2 and VOUT2). ∆VDO = VIN2 - VOUT2.
Note 6: IV5 = 0mA.
Note 7: tON time includes the delay and the rise time needed for IOUT to reach 90% of its final value. tOFF time is the time needed
for IOUT to drop below 10%. See the Typical Operating Characteristics. tON and tOFF are tested with 100Ω (MAX16815) or 51Ω (MAX16828) from OUT to CS+.
Note 8: Current regulation varies with V5 load (see the Typical Operating Characteristics).
Note 9: Thermal shutdown does not function if V5 is shorted to ground.
