Re: I need a charger schematic YLT6722000
Not sure if duty cycle would cause more ringing but if the frequency goes up the ringing would occur more often, but it's not frequency that determines energy transferred, it's duty cycle... though would be interesting what PWM chip this thing uses, can't read the chip number.
But it is weird that the MUR1060FCT (50ns recovery) is indeed an ultra fast recovery diode and not the FR207 (0.5µS recovery). Still doesn't beat that one SMPS PSU I had that actually did use a 1N4007 (30µs recovery) as the auxiliary power rectifier... That definitely got hot and fried itself...
