General Description

This AP1694A Triac Dimmable GU10 12V/400mA Buck LEDs driver EV board use tapped transformer to increasing power conversion turn on duty cycle, boost current back to LED during ratio of tapped winding. Also the bigger gauge wire can be used as well as the large inductance can be suitable in switching loop which can reduce the switching current and the lower forward drop so that SBR diode can be used which can reduce the power consumption on the diodes.
