MIC3230 Product details

General Description  

The MIC3230/1/2 are constant current boost switching controllers specifically designed to power one or more

strings of high power LEDs. The MIC3230/1/2 have an input voltage range from 6V to 45V and are ideal for a

variety of solid state lighting applications.



Features

• 6V to 45V input supply range

• Capable of driving up to 70W

• Ultra low EMI via dithering on the MIC3231

• Programmable LED drive current

• Feedback voltage = 250mV ±3%

• Programmable switching frequency (MIC3230/1) or 400kHz fixed frequency operation (MIC3232)

• PWM Dimming and separate enable shutdown

• Frequency synchronization with other MIC3230s

• Protection features:

   Over Voltage Protection (OVP)

   Over temperature protection

   Under-voltage Lock-out (UVLO)

• Packages:

• –40°C to +125°C junction temperature range



Applications

•Street Lighting

• Solid State Lighting

•General Illumination

•Architectural Lighting

• Constant Current Power Supplies
