Hi Team,
My customer evaluates it using the LM5033MM.
The external sync is working, but the duty is not close to 50%.
ON OFF Duty is 30% -70% operation, which is unstable operation which is 70% -30%.
If it is operated without a sync signal, it will operate at a Duty of nearly 50%.
Why is the operation unstable when a sync signal is input?
The surrounding conditions are as follows.
Rt / sync: 36kΩ-GND / 100pF-Sync (90kHz, 3.8V)
SS: 5V
COMP: Open
Ref: 0.1uF-GND
I also got the schematic from the customer and would like to send it in a private message.
Best Regards,
Kenji
