Part Number: UCC24636
our customer uses the UCC24636 for an industrial battery charger. The first version had an output voltage of 11-15.6V, so no problem.
In another project they are looking for a SR controller for 22-31V.
> Any chance to use the UCC24636 for the higher output voltage?
Does it have a similar internal clamp as the UCC24624 that can be used with an external resistor of 750Ohm?
Thanks and best regardsMartin

In reply to Benjamin Lough:
You could a resistor + zener to clamp the maximum voltage on the VDD pin. You will also want to make sure the VPC and VSC pins do not exceed their max voltage rating as well (abs max rating of 4.5V for both pins)
Another option is to have an additional bias winding to supply bias power to the controller. This would allow the driver to run a bit more efficiently than the above solution.
I'm not sure if your customer is planning to use low side or high side rectification but please share this SR controller configuration guide with them:
