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.

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.
