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.

IEC61000-3-2 spe iW3616兼容cification for electromagnetic compatibility (EMC), the Zhaga hot-plug standard, and incorporates mapping options that fall within the NEMA-6 SSL dimming curves. It also uses Dialog’s patented, intelligent digital dimming to automatically detect the dimmer type and phase, enabling broad compatibility with analog and digital dimmers. Dialog’s unique over-temperature protection (OTP) derating circuit monitors an external NTC resistor; reduces the output drive to the LEDs in small, virtually imperceptible increments; then restores brightness as temperature falls. This prevents exceeding the temperature rating of the electrolytic capacitors and helps ensure a predictable, safer bulb operating life. More on OTPhere.
