Part Number: LM27222
What guilde lines should I follow to select the bootstrap capacitor for a LM27222 driving 2 N-Channel FETS switching a 18 AMP load at 30HZ? This is to use the LM27222 as a replacement for the LM2726.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Randy Craft:
What device would TI recommend instead of the LM27222 as a replacement for the LM2726, if footprint-compatibility is NOT a constraint?
UCC27282 is our latest half-bridge driver, it is rated for -40C to 125C, includes a 5V UVLO and offers better drive current and switching characteristics.
The devices below are a good starting point.
