I'm using all 4 buck regulators and one of the LDO. The LDO output voltage is perfect but all 4 of the buck regulators output voltages are higher than configured. For example 1.0V is actually 1.2V, 3.3V is actually 3.8V
I noticed that the reference cap value on page 28 table 20 of datasheet is 2.2 uF while on page 61 table 34 recommends 220 nF (or 0.22 uF). Which is the correct value? Is this component critical? Can it be causing the voltage errors I'm seeing?
I have tried both the 2.2 uF and 220 nF values for Cref and made no difference. I still need some guidance as to what to look for with respect to Buck Regulator output voltages being 18% higher than configured while LDO voltages are accurate.
