So I've been learning about and improving all aspects of the boost converter, I recently had an epiphany learning about how MOSFETs turn on and off and how to simulate and estimate switching losses and how to select the most efficient one for the application.
I used my 100MHz (1GHz sample rate) Picoscope to measure the gate capacitance of a couple of MOSFETs by switching them off with a 1K resistor and a UCC27524 gate driver, 0.632 being the golden number to calculate the capacitance.
I also measured the switching time of the MOSFETs with the gate drive specs from the MP4008 datasheet so I could get an idea of the switching losses and add it to the resistance losses to calculate the efficiency.
But Now I've found what seems to be a newer and superior replacement for the MP4008 in the form of a Diodes Incorporated AL3353, it has a faster gate fall time and a slower oscillator frequency of 120KHz rather then 180KHz to reduce the switching losses as I dont need the boost converter to be very small.
There are a couple of things I cant figure out though, they dont mention a compensation network in the datasheet but rather "build-in slope compensation" with just a capacitor on the comp pin, thats a relief but I cant figure out what value the capacitor needs to be.
There is also a resistor to the CS pin called RSL and I cant figure out what that should be either, I have tried contacting them but they have not replied yet.
