I need your support in designing led driver for 3 leds, input 220V, output 700mA, 7,4W for switching and TRIAC dimmers.
I examined Design Examples and think that DER-302 (TRIAC Dimmable, Power Factor Corrected, 7.2 W Non-Isolated LED Driver, 185 VAC – 265 VAC Input) is the most suitable for my purpose. But it designed for 200mA leds.
On http://www.powerint.com/en/products/linkswitch-family/linkswitch-pl there is Device Selection Table from which I chose LNK457 (700mA, 3 leds). Could you help me to adoptise DER-302 for my purpose or advise some literature to read.
