I needed a driver for a small custom transformer for a special voltage. One channel of this device served the purpose very nicely. Using one channel, I built an H-bridge which I ran at 10kHz. I set the PWM duty cycle at continuous by connecting that input to the 5VDC power line, then controlled the direction input with a 50% duty cycle square wave. Handling the input at 12VDC, the IR3205 transistors were loafing with about 100 Watts of input. I thought a heat sink might be necessary, but they ran at only 45C with a 20C ambient! A nice feature of this controller is that it uses only N-Channel MOSFETs with high-side gate drivers. This makes the controller more efficient than using P-Channel MOSFETs on the high -side.
