主要应用
概述
The SSL2103 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from the rectified mains. It is designed to drive LED devices. The device includes a circuit to allow direct start-up from the rectified mains voltage. For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.
Applications
- SSL applications with various power requirements
- LED modules such as LED spots and down-lights
- LED strings suitable for retail displays, etc.
