Hello, I need some help connecting an 8 pin current mode PWM controller to my boost converter circuit. Specifically this one. I have used controller IC's with integrated switches to make boost converters before, however, the amount of power I need to run through the circuit requires an external MOSFET switch. A diagram of my boost converter circuit is below, I have tested the circuit with another IC (with an integrated switch and only 5 pins) and it works. I can figure out where some of the connections go (for the IC in question) but the purpose and use of the other 4 pins, COMP, VFB, RT/CT, and REF are beyond my understanding, I have read the entire datasheet. A diagram of the controller IC is also located below. Where and how do I connect the other 4 pins to the circuit? Thanks in advance!
