MIC3202/MIC3202-1  
High-Brightness LED Driver with  
Integrated MOSFET and High-Side  
Current Sense  
General Description  
Features  
The MIC3202 is a hysteretic, step-down, constant-current,  
High-Brightness LED (HB LED) driver. It provides an ideal  
solution for interior/exterior lighting, architectural and  
ambient lighting, LED bulbs, and other general illumination  
applications.  
• 6V to 37V input voltage range  
• High efficiency (>90%)  
• ±5% LED current accuracy  
• MIC3202: Dither enabled for low EMI  
• MIC3202-1: Dither disabled  
• High-side current sense (up to 1A)  
• Dedicated dimming control input  
• Hysteretic control (no compensation required)  
• Up to 1MHz switching frequency  
• Adjustable constant LED current  
• Over-temperature protection  
The MIC3202 is well suited for lighting applications  
requiring a wide-input voltage range. 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.  
The MIC3202 offers a dedicated PWM input (DIM) which  
enables a wide range of pulsed dimming. High-frequency  
switching operation of up to 1MHz allows the use of  
smaller external components, minimizing space and cost.  
The MIC3202 offers a frequency dither feature for low-EMI  
applications.  
• −40°C to +125°C junction temperature range  
Applications  
• Architectural, industrial, and ambient lighting  
• LED bulbs  
• Indicators and emergency lighting  
• Street lighting  
The MIC3202 operates over a junction temperature from  
−40°C to +125°C and is available in an 8-pin e-PAD SOIC  
package.  
• Channel letters  
A dither disabled version MIC3202-1 is also available in  
the same package as the MIC3202.  
• 12V lighting systems (MR-16 bulbs, under-cabinet  
lighting, garden/pathway lighting)
