Dimmable LED Driver IC with 650V MOSFET and PFC

IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ: IXYS), announced the immediate availability of the IX9907N high-voltage dimmable LED driver IC. Combining a 650V, 2-Ohm power MOSFET with a quasi-resonant controller, the IX9907N is optimized for off-line dimmable LED applications requiring a high power factor correction.

The IX9907N has a wide voltage operating range and low power consumption. Featuring a digital soft-start and foldback correction, and cycle-by-cycle peak current control, the IX9907N can drive LEDs with greater than 90% efficiency with a power factor correction of over 98%. Protection features include output over-current and over-voltage protection, over-temperature shutdown, and supply under-voltage lockout.

Applications include incandescent bulb replacement, solid state lighting, and industrial and commercial lighting. Available in a low-cost standard 8-pin SOIC package, the IX9907N is the latest addition to IXYS ICD’s portfolio of high-voltage LED drivers.
