TOP242 power source for 10W LEDs

Thursday, February 21st, 2013

Mincior over at Electroni-city built this DIY  TOP242 power source for 10W LEDs : Inside the case of a regular wall charger with a 500mA transformer I’ve built a source in commutation for powering 10W LEDs by using a TOP242 integrated circuit in the primary part and the LM393 dual comparator...
