High PF solid state dimmable LED driver up to 12W

The iW3616 two-stage SSL LED driver combines high power factor (PF > 0.95), low THD (< 15%) and low output ripple (< 20%) for residential and commercial dimmable retrofit LED luminaires up to 12W. By using a BJT power device, reducing component count for the protection circuits, and using lower-cost E-capacitors, the iW3616 enables a very low overall BOM cost.

IW3616与IEC61000-3-2的电磁兼容性（EMC），ZHAGA热插拔标准的规范兼容，并包含落在NEMA-6 SSL调光曲线内的映射选项。它还使用对话框的专利，智能数字调光，自动检测调光器类型和相位，从而实现与模拟和数字调光器的广泛兼容性。对话框的独特过温保护（OTP）降额电路监控外部NTC电阻;以小，几乎不可察觉的增量降低输出驱动器到LED;然后随温度下降恢复亮度。这防止了电解电容器的温度额定值，有助于确保可预测的更安全的灯泡使用寿命。更多关于OTP.这里.
