EVALUATION KIT AVAILABLE  
MAX16838B  
Integrated, 2-Channel, High-Brightness LED Driver  
with High-Voltage Boost and SEPIC Controller  
General Description  
Benefits and Features  
● High Integration Provides for a Compact Solution  
• Integrates 2-Channel, 20mA to 150mA Linear LED  
Current Sinks  
The MAX16838B is a dual-channel LED driver that inte-  
grates both the DC-DC switching boost regulator and two  
150mA current sinks. A current-mode switching DC-DC  
controller provides the necessary voltage to both strings  
of HB LEDs. The device accepts a wide 4.75V to 40V  
input voltage range and directly withstands automotive  
load-dump events. For a 5V ±10% input voltage, connect  
• Internal Slope Compensation and Switching  
MOSFET  
● Flexible IC Fits Many Applications  
• Boost or SEPIC Converter Topologies  
• Wide 4.75V to 40V or 5V ±10% Input Operating  
• Range  
V
IN  
to V . The wide input range allows powering HB  
CC  
LEDs for small-to-medium-sized LCD displays in automo-  
tive and display backlight applications.  
• 200kHz to 2MHz Resistor-Programmable Switching  
Frequency with External Synchronization  
An internal current-mode switching DC-DC controller  
supports the boost or SEPIC topologies and operates  
in an adjustable frequency range between 200kHz and  
2MHz. The current-mode control provides fast response  
and simplifies loop compensation. The device also fea-  
tures an adaptive output-voltage adjustment scheme  
that minimizes the power dissipation in the LED current-  
sink paths. The MAX16838B can be combined with the  
MAX15054 to achieve a buck-boost LED driver with two  
integrated current sinks.  
● Wide Contrast Ratio Ideal for High Quality TFT and  
Head-Up Displays  
• PWM Dimming Ratio of 10,000:1 at 200Hz  
● Robust with Respect to Temperature and Fault  
Conditions  
• Current Foldback Reference Input  
• LED Open/Short Detection and Protection  
• Output Overvoltage and Overtemperature  
Protection  
The channel current is adjustable from 20mA to 150mA  
using an external resistor. The external resistor sets both  
channel currents to the same value. The device allows  
connecting both strings in parallel to achieve a maximum  
current of 300mA in a single channel. The MAX16838B  
also features pulsed dimming control with minimum pulse  
widths as low as 500ns on both channels through a logic  
input (DIM).  
• Thermally Enhanced 20-Pin TSSOP (4.4mm) and  
TQFN (4mm x 4mm) Packages  
Typical Operating Circuit and Ordering Information appear at  
end of data sheet.  
The  
device  
includes  
output  
overvoltage  
protection, open-LED/shorted-LED detection, and  
overtemperature protection. The device is available in  
20-pin TSSOP (4.4mm) and TQFN (4mm x 4mm) pack-  
ages and operates over the -40ºC to +125ºC automotive  
temperature range.
