Add lower value capacitors to output of boost converter #16

Closed XDjackieXD closed 2 years ago

XDjackieXD commented 3 years ago

The higher the capacitance, the higher the ESR. This is why you usually chain different values of capacitors for switch mode converter noise rejection (for example 100nF, 1µF, 10µF, 100µF is a usual arrangement). Currently there are only four 68µF capacitors. I'd suggest adding a 100nF and 1µ in front of it and maybe something in the range of 4.7-10µF

Capacitor Values and ESR for those capacitors where calculated by the Texas Instruments workbench. Since no minimum ESR is given in the datasheet adding a capacitor with lower ESR should be ok to reduce noise.
