Hi,
i`m gonna to post hi-end class D pwm base on IR2110 + LM311 for UCD style and IR2110 + TL074 for non-UCD style. This amp already tested and i`ll post for both circuit + pcb + silk. Most of us already understand when implement into class D pwm will face few adjustment to apply with suiteable power rails. Also to measure dc at output is omportant because it can burn @ damage your speaker without correct connection. My suggestion if u include dc protection for this amp and if u can apply short circuit protection connect to SD mode at IR2110. Unfortunately i`m not done yet with SD protection and only depends on fuse at each rails + DC protection. So far so good and never blow any mosfet yet since 1 year running this module. I`ve build both UCD and Non-UCD style, nothing much different, but with LM311 we need good filter at input signal. Its very sensitive pwm need to proper filter to avoid any EMI with others electronic devices.
Credits goes to owner ejtagle from foros de electronica forum . here you go for hi power class D pwm module. I believe there are many modules on the net and also here in diysmps forum. I hope all of u like it.
regards.
