gate driver circuits (charge pump based) for dc-dc ??

Hello, I need to design a CMOS based gate driver circuit for buck dc-dc converter. A bootstrap capacitor based architecture is needed . Does anyone know useful papers or documents for this ?

Thanks..........

What have you found so far?

What have you tried so far?

Major vendors' collateral for half bridge drivers ought
to give you at least crude schematics. Like IR2110,
HIP2100, HIP4080 (full bridge). Although at lower
voltages you may not like eating the bootstrap diode
Vf, and maybe prefer a synchronous switch, that can
get messy quick.

A lot of the design will be steered by what input and
logic supply voltage, what current, what frequency
and what gate terminal slew rate you intend to have.
One size does not fit all.

Hello, the application note by Laszlo Balogh is fine. But I am looking for papers that have a real CMOS based implementation of a charge pump based bootstrap gate driver. Any papers you can suggest ?

Try to be a little more specific about your design. Are
you talking something like an integrate POL buck where
you "own" all of the switches? Looking to use a NMOS
high side presumably, so need an over-the-rail charge
reservoir, do you have SOI or some HV elements that
can let it fly like it needs to? Figuring (for a 5V example)
your high side could see +11V if a lossless (sync) diode,
have you got components rated that high above the
substrate potential, if junction isolated?

I've seen (not done, but evaluated) an all NMOS buck
with sycnhronous bootstrap switch but that was all
an internal, proprietary boondoggle for a company I
no longer work for. On SOI. I know outfits like TI make
5V POLs with bootstrap high sides that work for them
(probably HV wells, and LDMOS either engineered or
opportunistic).

Papers will give you the start, but this kind of thing is
always about the hidden flaws / gotchas in the end.
Which management will never let you publish.
