MT7603

DESCRIPTION
MT7603 is a high voltage linear constant-current LED driver. It’s designed to drive LED string directly from 110VAC/220VAC mains.
The system can easily pass EMI without inductor, transformer or other magnetic components, it can achieve simplified peripheral circuit and low BOM cost. The application of high power can be achieved by controlling the MOS temperature. The output current can be set by external resistor. With Maxic’s proprietary linear compensation technology, MT7603 can achieve constant power output when the input voltage is variable.

FEATURES
Supports high power application with external MOS
High precision constant current
Supports linear voltage compensation
Both of With/without electrolytic capacitor schemes are supported
High power factor application
Low EMI interference
Available in SOT23-6 package
