Commercial lighting makers are constantly looking for a low cost, simple solution for their lighting applications. To cater to this demand, Avnet has brought out a low BOM cost solution for dimmable commercial T8, external and fixture driver lighting applications.
The design includes a 0-10V dimmable single-stage (Flyback), high-performance LED driver utilizing the iW3636 primary-side controller and the iW339 secondary-side dimming interface IC. It also comes with High PF and Low THD. And output current is a constant 1,000mA over a voltage range of 20V to 40V. Working from a universal input range of 90V (AC) to 305V (AC), this design offers high efficiency and constant regulation across the output range.
