High-Voltage, 100mA/200mA Adjustable Linear
High-Brightness LED Drivers with PWM Dimming
5/MAX1628
General Description
Features
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 dim-
ming input allows wide-range “pulsed” PWM operation.
An on-board pass element minimizes external compo-
nents while providing ±±.5ꢀ output-current accuracy.

Stresses 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.

Detailed Description
Applications Information
+5V Regulator
The MAX16815/MAX16828 include a fixed +5V output
regulator that delivers up to 4mA of load current
throughout the 6.5V to 40V input voltage range.
Connect a 0.1µF compensation capacitor from V5 to
ground. Shorting V5 to ground disables the thermal
shutdown. V5 stays on during PWM dimming.
Programming the LED Current
The MAX16815/MAX16828 use a sense resistor across
CS+ and GND for the TDFN package or across CS+
and CS- for the SO package, to set the LED current.
The LED current is given by I
= V
/R
.

Input-Voltage Considerations
For proper operation, the minimum input voltage must
always be:
Thermal Protection
The MAX16815/MAX16828 enter a thermal-shutdown
mode in the event of overheating. This typically occurs
in overload or output short-circuit conditions. If the
V
≥ V
+ V + ∆V (MAX)
FT(MAX) DO
IN(MIN)
RSNS(MAX)
where V
is the total forward voltage of all series
FT(MAX)
connected LEDs. The minimum operating voltage of the
device is +6.5V. The device operates below +6.5V;
however, output current may not meet the full regulation
specification (see the Typical Operating Characteristics)
and the V5 regulator will drop below 5V.
junction temperature exceeds T = +159°C (typ), the
J
internal thermal-protection circuitry turns off the series
pass device. The MAX16815/MAX16828 recover from
thermal-shutdown mode once the junction temperature
drops by 24°C (typ). The devices therefore protect
themselves by thermal cycling in the event of a short-
circuit or overload condition. Shorting V5 to ground dis-
ables the thermal shutdown.
Low-Frequency PWM Dimming
at the Output
Provide a pulse to the dimming input (DIM) of the
MAX16815/MAX16828 to produce a PWM output.
Alternatively, connect DIM to IN and pulse IN.

Figure 1 shows PWM dimming operation for the
MAX16815/MAX16828 with an ICM7555 timer. The
ICM7555 provides adjustable duty cycle using two
external resistors and a capacitor. In TAIL operation,
the output of the ICM7555 feeds into DIM and lights up

LED Current Thermal Foldback
With a minimum number of external components, the
MAX16815/MAX16828 provide LED current thermal
foldback using a negative temperature coefficient
(NTC) thermistor. Figure 2 shows a thermistor connect-
ed to V5 and the CS+ of the MAX16815/MAX16828. As
the temperature increases, the voltage drop across R2
increases, causing the LED current to decrease.

Thermistor

set by a parallel combination of R1 and R2. Figure 4

Multichannel HB LED Driver
Figure 5 shows an array of MAX16815/MAX16828s with
independent DIM control. The MAX5094C, a current-
mode PWM controller, provides the input power to each
LED driver preregulated voltage to multiple MAX16815/
MAX16828 drivers.
