Integrated 16-Channel LED Driver with Switch-Mode Boost and SEPIC Controller
General DescriptionThe MAX16809 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 MAX16809’s current-mode PWM control-
ler regulates the necessary voltage to the LED array.
Depending on the input voltage and LED voltage range,
this device can be used with boost or buck-boost (SEPIC)
topologies.
The MAX16809 LED driver includes 16 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 dimming
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 MAX16809 operates either in stand-alone mode or
with a microcontroller (µC) using an industry-standard,
4-wire serial interface.
The MAX16809 includes overtemperature protection,
operates over the full -40°C to +125°C temperature range,
and is available in a 5mm x 7mm thermally enhanced,
38-pin TQFN exposed pad package.

Each)●±3% Current Matching Among Outputs●Paralleling Channels Allows Higher Current per LED
String ●Outputs Rated for 36V Continuous Voltage●Output-Enable Pin for PWM Dimming (Up to 30kHz)●One Resistor Sets LED Current for All Channels●Wide Dimming Ratio Up to 5000:1●Low Current-Sense Reference (300mV) for High
Efficiency●8V to 26.5V Input Voltage or Higher with External
Biasing Devices●4-Wire Serial Interface to Control Individual Output
