I saw you forum concerning the class d power using the if2110 driver. Have got a project 4 class d power amplifier, am using if2110 ic driver to drive the mosfet,
The problem is i dont know how to connect the PWM signal to the if2110, I have seen HI and LO inputs. how can i connect. help me!!!!

The IR2110 has HI and LO input because those control the FETs. Your 2 PWM signals connect to the LO and HI inputs to drive the FETs. When LO is high, the lower FET is on, and when HI is high, the upper FET is on. The 2 PWM signals are your standard class AD or BD modulation, with dead time of course. Good luck.
The datasheet should have explained that for you, I'd recommend you start reading them if you want to make a class d amp happen.
Secondly since you're curious to use the IR driver chips you might look at how they've implemented it themselves, perhaps there's some sort of an evaluation board or something you can look at? They might even have a good write up to go with it, should look for something like that.
