Hello Brian,
The register setup/OTP defaults are in the Technical Reference Manuals for the particular orderable part number.

Hi Tomi,
thanks for quick reply!
Just to be sure, if customer is not using any of the default setting, they are fine to go with LP87561IRNFTQ1 instead of LP875610RNFTQ1.
Or anything else I should mention to customer?
Thanks!

Hi Brian,
Yes they are free to use either one if they use I2C to configure the registers before turning on the bucks. However the LP875610RNFTQ1 has the reset register interrupt enabled which can be handy to inform the host that something has reset the registers (momentary power glitch for example) and they are back to default. Host can then reconfigure the registers through I2C and clear registers.
You can check the configuration guide for more details: https://www.ti.com/lit/ug/snvu590/snvu590.pdf
Thanks.
