LED Driver for 4W and 8W dimmable replacement bulbs

The iW3662 SSL LED driver offers universal transformer compatibility and good dimmer compatibility for MR16 and other low-voltage lighting applications even with output power as low as 4W.

集成在iW3662中的Dialog数字控制技术实现了与电子和磁性变压器的兼容性。iW3662自动检测变压器类型并动态增加峰值负载以锁定变压器，确保与传统电子变压器兼容，这是MR16 LED更换灯泡的最大困难。iW3662还检测并使用几乎所有的调光器，调光范围从5%到100%。

全套保护功能包括Dialog独特的超温保护（OTP）降额功能，该功能可监控密封LED灯泡内部的温度，并在温度升至安全工作阈值以上时无缝减少LED的驱动，然后在温度下降时恢复亮度。iW3662集成了温度传感器，允许用户配置OTP阈值。更多关于OTP在这里.
