💡 SM2213EK Dimming & Color Temperature Adjustable Linear Constant Current LED Driver – Now in Stock
We are pleased to announce the availability of the SM2213EK linear constant current LED driver IC from Sunmoon Microelectronics. This highly versatile IC integrates switch dimming and color temperature adjustment functions in a single chip, making it ideal for modern LED lighting applications.
With built-in high-voltage MOSFET and JFET power supply, the SM2213EK simplifies LED driver design while delivering reliable, flicker-free performance for T5/T8 tubes, bulbs, and ceiling lamps.
💡 What is the SM2213EK?
The SM2213EK is a linear constant current LED driver IC that supports both switch dimming (3-stage brightness control) and color temperature adjustment (3-stage CCT switching between two LED color strings). It integrates high-voltage MOS tubes and a JFET high-voltage power supply, reducing external component count and simplifying PCB design.
Using a standard wall switch, users can cycle through 100% → 50% → X% brightness (dimming mode) or 2700K → 4000K → 6500K (color temperature mode) with each quick on/off toggle.
✨ Why Choose the SM2213EK?
- 🔀 Dual Functionality – Supports both 3-stage dimming and 3-stage color temperature adjustment in a single IC
- ⚡ Integrated High-Voltage MOSFET – Built-in 500V MOS tube reduces external components and BOM cost
- 🎯 Adjustable Output Current – Each channel (OUT1, OUT2) independently adjustable up to 70mA via external resistors
- 🔄 Quick Switch Detection – Fast response to wall switch toggles for smooth mode transitions
- 🌡️ Overtemperature Protection – Built-in temperature compensation reduces current at 140°C to protect LEDs and extend lifespan
- 🔌 Wide Input Voltage – Compatible with 120Vac and 220Vac mains
- 📦 ESOP8 Package – Enhanced thermal dissipation for reliable operation
- 🎯 High Current Accuracy – ±6% current deviation between ICs ensures consistent performance
