MIC3201  
High Brightness LED Driver with  
High-Side Current Sense  
General Description  
Features  
The MIC3201 is a hysteretic step-down, constant-current,  
High-Brightness LED (HB LED) driver capable of driving  
up to four, 1A LEDs. It provides an ideal solution for  
interior/exterior lighting, architectural and ambient lighting,  
LED bulbs, and other general illumination applications.  
• 6.0V to 20V input voltage range  
• High efficiency (>90%)  
• ± 5% LED current accuracy  
• High-side current sense  
• Dedicated dimming control input  
• Hysteretic control (no compensation!)  
• 1A internal power switch  
• Up to 1MHz switching frequency  
• Adjustable constant LED current  
• 5V on board regulator  
The MIC3201 operates with an input voltage range from  
6V to 20V. The hysteretic control gives good supply  
rejection and fast response during load transients and  
PWM dimming. The high-side current sensing and on-chip  
current sense amplifier delivers LED current with ±5%  
accuracy. An external high-side current sense resistor is  
used to set the output current.  
• Over temperature protection  
• –40°C to +125°C junction temperature range  
• Available in an 8-Pin ePAD SOIC package  
The MIC3201 offers a dedicated PWM input (DIM) which  
enables a wide range of pulsed dimming. A high switching  
frequency operation up to 1MHz allows the use of smaller  
external components minimizing space and cost.  
The MIC3201 operates over a junction temperature range  
of -40°C to +125°C and is available in an 8-pin ePAD  
SOIC package.  
Applications  
• Architectural, industrial, and ambient lighting  
• LED bulbs  
• Indicators and emergency lighting  
• Street lighting  
Datasheets and support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
• Channel letters  
• 12V lighting systems (MR-16 bulbs, under cabinet  
lighting, garden/pathway lighting)
