Hello,
I have done a development with a LM63610DQPWPRQ1. It is a bit of an unusual application where I am actually using a high inductance proportional valve solenoid for the inductor.
In a previous forum, I was directed to this part because I needed forced PWM even at low currents.
It works great for my application.
Now we are doing another prototype run and find that lead times on the LM63610DQPWPRQ1 are terrible, extending into 2022.
I know that the LM63615DQDRRRQ1 is pin compatible but 1.5A instead of 1.0A I can get this part.
Is the current the only difference?
With a 0.04H (40millihenry) inductance and being forced PWM at 250 KHZ, there is simply no chance of reaching the peak current of the LM63615DQDRRRQ1, but honestly, I was not reaching the peak current on the LM63610DQPWPRQ1 either. From what see on the specs, the peak current is the only difference.
But the forced PWM cuts off the current before it ever reaches the peak value.
Do you agree?
Can you tell me of any problems I might run into going to the 1.5A part?
Since the only package I can get is the WSON and I had the HTTSOP I cannot just try it out.
Oh yeah...my max continuous current is 0.5A.
Thanks
Glen
