Full Bridge PWM controller w/ Integrated Gate Drvrs

TechGuy · 25th December 2008, 07:17 PM

I am looking for a Full H-Bridge PWM controller that includes gate drivers to minimize PCB real estate. Does anyone know if such a controller exists? The closest I've found is IRS2453D which is a Self-oscillating H-Bridge Driver but without feedback. As an alternative a half bridge PWM controller with Integrated gate drivers would also work.

Thanks

Look at ST's L6598 is only half bridge but it does have integrate drivers.

Thanks for the tip! That might work fine.

I asked a tech-rep from Motorola a while back about this (before the OnSemi spin-off): Is there a PWM with an integrated floating driver for the high-side switch? Answer was not at that time, nor any plans to do so. The only chip I ever dsaw with SMPS control and the driver chip together was either a ZVS or ZCS chip and I can't remember the mfr. OnSemi's new line of high-voltage driver ICs look interesting. O, if only they would get back into making high-voltage (400Vdss+) MOSFETs!

Cheers,

Steve
