TOP242 power source for 10W LEDs

Posted on Thursday, February 21st, 2013 in DIY by DP


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 on low voltage.

    That is an interesting extruded heatsink with spring-clip on the power package, have not seen that style before.
