品佳集团力推NXP 25W LED Dimming Driver IC Solution

 2009-07-29
NXP SSL2101/SSL2102是一个体积小、高整合度及效率高的LED driver,支援可调光(TRIAC and Transistor)及实现小体积的应用。

SSL2102是NXP主推的一颗高整合度的LED driver,整合了控制IC与MOSFET;SSL2101/SSL2102可以使用在隔离式(flyback)与非隔离式(buck)应用;SSL2101/SSL2102 在散热上也做了改进,故在散热有不错的表现,是LED在Lighting应用上最佳solution。

SSL2101/SSL2102皆有OCP(Over-temperature protection)、OTP(Over-current protection)、SWP
(Short-winding protection)的保护功能,这在lighting追求小且散热佳上,提供了一了最适当的protection。

Features:
‧High efficiency and high power-factor for SSL applications below 25 W
‧Natural dimming curve via logarithmic correction
‧Supports the majority of available dimmers in the market (e.g. TRIAC, transistor)
‧Limited external components required due to high integration level, ideal for small form-factor applications with closed casing
‧Switched SMPS controller with buck and flyback configurations
‧Thermally enhanced SO20 wide-body 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

Applications:
‧SSL retrofits (e.g. GU10, E27) from 8 to 15 W
‧LED modules (e.g. LED spots, down lights) from 15 to 25 W
Note: for power ratings below 15 W (for LED modules) and 8 W (for SSL retrofit), NXP offers the SSL2101.
SSL2101 is direct compatible with SSL2102 which simplifies engineering
