有关 iW3623 的资源
描述
The iW3623 is a high-performance, two-stage, non-dimmable 45W Solid-State Lighting (SSL) LED driver that integrates boost and flyback converters into a single IC to reduce BOM cost and simplify design versus conventional two-stage driver approaches. Compliant to the IEC 61000-3-2 standard, the iW3623 offers a Power Factor (PF) of >0.95 from a universal input voltage of 100VAC to 277VAC, with Total Harmonic Distortion (THD) <10% and low output ripple <5% over the entire range.
The iW3623 incorporates Renesas' proprietary PrimAccurate™ primary-side control technology, eliminating the need for a secondary-side regulator and optical feedback isolator. It also allows FETs to be replaced with lower cost bipolar junction transistors (BJTs) and uses quasi-resonant mode switching for both the boost and flyback stages and dynamic base current to optimize conversion efficiency and minimize EMI.
Protection features include an on-board, external NTC-based temperature protection circuit that reduces the output drive to the LEDs to protect the circuit from overheating while maintaining light output.
