SSL2103設計的可調(diào)光LED照明技術

本文介紹了SSL2103主要特性和優(yōu)勢, 方框圖以及降壓穩(wěn)壓器配置圖和反激電源配置圖.

SSL2103用于可調(diào)光LED照明的開關電源(SMPS)控制器,是一款多用途AC/DC LED照明控制器, 具有更寬的功率適用范圍和更好的調(diào)光兼容性，令其適用于可調(diào)及不可調(diào)LED照明燈。SSL2103針對更高功率的LED照明燈具（PAR20、PAR30和PAR38）而設計，為LED燈具設計者在功率、外形尺寸及調(diào)光控制方面提供完全的靈活性。

SSL2103主要特性和優(yōu)勢:

Easy migration to existing lighting control infrastructures, TRIAC and transistor
dimmers

Compatible with most dimming solutions

Optimized efficiency with valley switching managed by built-in circuitry

Built-in demagnetization detection

Built-in OverTemperature Protection (OTP)

Short-Winding Protection (SWP) and OverCurrent Protection (OCP)

Internal VCC generation allowing start-up from rectified mains voltage

Natural dimming curve by logarithmic correction, optimized for human eye response,
down to 1 %

SSL2103應用:

The SSL2103 is suitable for various power requirements including:

Retro-fit lamps

LED modules such as LED spots and down-lights

LED strings suitable for retail displays etc.
