Other Parts Discussed in Thread: UCD3138
I am looking at PMP21529 and am considering basing a new design off of it.
A few questions:
- It talks about max VIN and VOUT being 60V. I'm hoping that by tweaking R1, R2, R9 and R10 I could have a 48V bus voltage exchanging power with a 12V lead acid battery voltage. Please confirm.
- I see it uses low side current sensing. Any comments on why this was chosen? I would need high side sensing so that the systems have a common ground.
This will work for a PoC of the product. Eventually I will need an isolated bi-directional buck boost. Do you have any reference designs for isolated, bi-directional buck boosts? (48V<->12V, 100W to 500W range)
