SSL2101 - Mains LED Driver for dimmable LED Lighting
This small, highly integrated and highly efficient driver is the next step in SSL retrofit LED lighting. It supports the majority of available dimmers (TRIAC and transistor) and is ideal for small form-factor applications with closed casings.
The SSL2101 is a Switched Mode Power Supply (SMPS) controller IC that operates directly from rectified mains and also in combination with a phase cut dimmer. It is designed to drive LED devices. The device includes a high-voltage power switch and a circuit to allow start-up directly from the rectified mains voltage. Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer. For dimmable applications, integrated dedicated circuitry optimizes the dimming curve.
Features
- High-efficiency and high power-factor for SSL applications below 15 W
- Natural dimming curve via logarithmic correction
- Supports the majority of available dimmers in the market (e.g. TRIAC, transistor)
- Fewer external components due to high integration level, ideal for small form-factor applications with closed casing
- Switched SMPS controller with buck and flyback configurations
- Thermal-enhanced & small SO16 package
- Meets safety and power-factor regulations
- Optimized valley switching with built-in, dedicated circuitry
- Built-in magnetization detection
- Built-in protection circuitry
- Supports start-up from rectified mains voltage
Key Applications
- SSL retrofits (e.g. GU10, E27) from 3 W to 8 W
- LED modules (e.g. LED spots, down lights) from 8 W to 15 W
