描述 Description

The SSL2102 is a Switched Mode Power Supply (SMPS) driver 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 high-voltage power switch, a circuit to allow start-up directly from the rectified mains voltage and a high-voltage circuitry to supply the phase cut dimmer. For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.

特性 Features
