Re: New IR Driver Chip

WOW!!

That looks like a DRSSTC on a chip!!

The drive current is a little low but there "is" time to charge a bridge 5nF gate with the nice 1uS crossover delay!

Weeeee!!!

This is a URL to a new full bridge 600V driver available from International
Rectifier.  The half bridge (original) IRS21531D has now been supplemented
with this NEW part (IRS24531D) which is a isolated full bridge, driven by
an RC "555 type" oscillator with undervoltage lockout, and latched and
active shutdown. Looks very intriguing for DRSSTC, hard driven SSTC, and perhaps DC to HVDC converters. Can definitely drive FET's and perhaps
small IGBT's for halogen / HID ballasts.
