NXP Semiconductors announced the launch of the SSL2101 an integrated dimmable mains LED driver. The SSL2101 is a small form factor Switched Mode Power Supply controller IC specifically designed to drive LED devices and provide dimming capabilities of LED lighting. The SSL2101 can drive lighting systems with variable power requirements which include LED retro-fit lamps, LED modules, LED spots, down-lights and LED strings for retail displays.

The SSL2101 is fully compatible with today’s lighting infrastructure and can operate directly from rectified mains power supply in combination with a phase cut dimmer. It includes a high-voltage power switch and can start-up directly from the rectified mains voltage. To support its dimming capabilities the SSL2101 contains two integrated high voltage-switches for bleeder operation and an input that can be used to sense lamp power usage and activate additional bleeder action when needed.

The SSL2101 also offers non-isolated (buck) and isolated (fly-back) solutions in one chip. It has an additional input that can be used to detect demagnetization of the inductive element, ensuring full utilization of the magnetic material and preventing hard switching of the current. The device has in-built circuitry to reduce capacitive switch-on losses and optimize valley switching efficiencies therefore making the SSL2101 an effective power converter at low power levels.

The SSL2101 is available in Europe, US, APAC and Japan. The price per piece is $1.50 (USD).
