Hello Terry,

It should be able to provided the design is correct. Since it is not synchronous the freewheel diodes will have to be size according to the LED current and the freewheel diode duty cycle which looks to be fairly high in this design.

Hello Irwin,

Non-synchronous freewheel diode is a problem .
