Schematic above
VIN : 48V, (Min 46V~Max 52V)
PWM spec : 3.3V 20KHz 1024step
Dimming100%, between L2 and D7
VIN : 52V, (Min 46V~Max 52V)
PWM spec : 3.3V 20KHz 1024step
Dimming100%, between L2 and D7
When Vin increases and begins to exceed 50V, flicker occurs.
OFF interval occurs in Vsw waveform.
Where should I adjust?
