MIC4801  
High Efficiency 600mA Single Channel  
Linear WLED Driver with  
Ultra Fast PWM™ Control  
General Description  
Features  
The MIC4801 is a high efficiency White LED (WLED)  
driver designed to drive a single LED up to 600mA. The  
MIC4801 constant current driver is designed to drive high  
power LED’s in various lighting applications. The MIC4801  
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 130mV at 400mA. 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 130mV at 400mA  
• Programmable LED current with external resistor  
• Current accuracy of ±1% typical  
Applications  
• Bill board displays  
• Marquee displays  
• Instrument displays  
• Architectural lighting  
The MIC4801 is available in an 8-pin SOIC package with a  
junction temperature range of -40°C to +125°C.
