EVALUATION KIT AVAILABLE  
2MHz, High-Brightness LED Drivers  
with Integrated MOSFET and  
High-Side Current Sense  
MAX16832A/MAX16832C  
General Description  
Benefits and Features  
• Cost-Effective Solution for a Wide Range of LED  
Lighting Applications  
The MAX16832A/MAX16832C step-down constant-cur-  
rent high-brightness LED (HB LED) drivers provide a  
cost-effective design solution for automotive  
interior/exterior lighting, architectural and ambient light-  
ing, LED bulbs, and other LED illumination applications.  
• 6.5V to 65V Input Voltage Range  
• Output Current Up to 1A  
•
3ꢀ LED Current Accuracy  
The MAX16832A/MAX16832C operate from a +6.5V to  
+65V input voltage range and can provide an output  
current up to 700mA, if operated up to a temperature of  
+125°C, or up to a 1A if operated up to a temperature  
of +105°C. A high-side current-sense resistor adjusts  
the output current, and a dedicated pulse-width modu-  
lation (PWM) input enables pulsed LED dimming over a  
wide range of brightness levels.  
• Selectable Dimming Options: Linear or PWM  
• Minimal Component Count Saves Cost and Space  
• On-Board 65V, 0.45Ω Power MOSFET  
• Resistor-Programmable Constant LED Current  
• Integrated High-Side Current Sense with 200mV  
Current-Sense Reference  
• Hysteretic Control: Up to 2MHz Switching  
These devices are well suited for applications requiring  
a wide input voltage range. The high-side current sens-  
ing and an integrated current-setting circuitry minimize  
the number of external components while delivering an  
average output current with 3ꢀ accuracy. A hysteretic  
control method ensures excellent input supply rejection  
and fast response during load transients and PWM dim-  
ming. The MAX16832A allows 10ꢀ current ripple, and  
the MAX16832C allows 30ꢀ current ripple. Both  
devices operate up to a 2MHz switching frequency,  
thus allowing the use of small-sized components.  
Frequency  
• Protection Features and Wide Operating  
Temperature Range Improves Lighting Fixture  
Reliability  
• Thermal-Foldback Protection Dims LEDs to  
Minimize Overheating  
• Thermal-Shutdown Protection  
• Available in a Thermally Enhanced 8-Pin SO Package  
• Operation over -40°C to +125°C Temperature Range  
The MAX16832A/MAX16832C offer an analog dimming  
feature that reduces the output current by applying an  
external DC voltage below the internal 2V threshold volt-  
age from TEMP_I to GND. TEMP_I also sources 25µA to  
a negative temperature coefficient (NTC) thermistor con-  
nected between TEMP_I and GND, thus providing an  
analog thermal-foldback feature that reduces the LED  
current when the temperature of the LED string exceeds  
a specified temperature point. Additional features  
include thermal-shutdown protection.  
Ordering Information and Pin Configuration appear at end  
of data sheet.
