MIC4802  
High Efficiency 800mA Single Channel  
Linear WLED Driver with  
Ultra Fast PWM™ Control  
General Description  
Features  
The MIC4802 is a high efficiency White LED (WLED)  
driver designed to drive a single LED up to 800mA. The  
MIC4802 constant current driver is designed to drive high  
power LED’s in various lighting applications. The MIC4802  
provides the highest possible efficiency as this architecture  
has no switching losses present in traditional charge  
pumps or inductive boost circuits. It features a typical  
dropout of 280mV at 800mA. This allows the LEDs to be  
driven directly from the voltage source eliminating  
switching noise/losses present with the use of boost  
circuitry. The high accuracy (±1% Typical) current  
regulated WLED channel ensures uniform display  
illumination under all conditions. The brightness is  
controlled through an Ultra Fast PWM™ Control interface  
operating down to less than 1% duty cycle.  
• High Efficiency (no Voltage Boost losses)  
• Ultra Fast PWM™ control (200Hz to 500kHz)  
• Input voltage range: 3.0V to 5.5V  
• Dropout of 280mV at 800mA  
• Programmable LED current with external resistor  
• Current accuracy of ±1% typical  
Applications  
• Bill board displays  
• Marquee displays  
• Instrument displays  
• Architectural lighting  
The MIC4802 is available in the 8-pin SOIC Epad package  
with a junction temperature range of -40°C to +125°C.
