UCC25660: Bootstrap Capacitor Charging

Part Number: UCC25660

Tool/software:

Hi,

With the old controller UCC25640x, the bootstrap capacitor is charged with a long lower-gate pulse during startup.

How is this capacitor charged with the newer controller UCC25660x? Is it the same way with a long LO pulse? I couldn't find this information in the datasheet.

Kind regards,

Ahmad
