MIC3203/MIC3203-1  
High-Brightness LED Driver Controller  
with High-Side Current Sense  
General Description  
Features  
The MIC3203 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.  
• 4.5V to 42V input voltage range  
• High efficiency (>90%)  
• ±5% LED current accuracy  
• MIC3203: Dither enabled for low EMI  
• MIC3203-1: Dither disabled  
• High-side current sense  
• Dedicated dimming control input  
• Hysteretic control (no compensation!)  
• Up to 1.5MHz switching frequency  
• Adjustable constant LED current  
• Over-temperature protection  
The MIC3203 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 MIC3203 offers a dedicated PWM input (DIM) which  
enables a wide range of pulsed dimming. A high-frequency  
switching operation up to 1.5MHz allows the use of smaller  
external components minimizing space and cost. The  
MIC3203 offers frequency dither feature for EMI control.  
• −40°C to +125°C junction temperature range  
Applications  
• Architectural, industrial, and ambient lighting  
• LED bulbs  
• Indicators and emergency lighting  
• Street lighting  
The MIC3203 operates over a junction temperature from  
−40°C to +125°C and is available in an 8-pin SOIC  
package.  
A dither disabled version MIC3203-1 is also available in  
the same package as the MIC3203.  
• Channel letters  
• 12V lighting systems (MR-16 bulbs, under-cabinet
