Integrated 8-Channel LED Driver with
Switch-Mode Boost and SEPIC Controller
General Description
The MAX16807 is an integrated, high-efficiency white or
RGB LED driver. It is designed for LCD backlighting
and other LED lighting applications with multiple strings
of LEDs. The MAX16807 current-mode PWM controller
regulates the necessary voltage to the LED array.
Depending on the input voltage and LED voltage
range, it can be used with boost or buck-boost (SEPIC)
topologies. The MAX16807 features an 8V to 26.5V
input voltage range. A wide range of adjustable fre-
quency (20kHz to 1MHz) allows design optimization for
efficiency and minimum board space.
The MAX16807 LED driver includes eight open-drain,
constant-current-sinking LED driver outputs rated for
36V continuous operation. The LED current-control cir-
cuitry achieves ±3% current matching among strings
and enables paralleling of outputs for LED string cur-
rents higher than 55mA. The output-enable pin is used
for simultaneous PWM dimming of all output channels.
Dimming frequency range is 50Hz to 30kHz and dim-
ming ratio is up to 5000:1. The constant-current outputs
are single resistor programmable and the LED current
can be adjusted up to 55mA per output channel.
The MAX16807 operates either in stand-alone mode or
with a microcontroller (μC) using an industry-standard, 4-
wire serial interface.
The MAX16807 includes overtemperature protection,
operates over the full -40°C to +125°C temperature
