I have faced strange behaviour of one of four LTM8067 in my scheme. I have two channels(ch1 and ch2) in my design, each has 2 ltm8067: one for 5.0V output and one for 3.3V output. With LTM8067 for 5V0 out I have no problems at all, but one of 3.3V LTM8067 performs unusial: it has 2.4Vout instead of 3.3V as defined via 11.8k resistor on FB pin. Also I see huge pulsations on output voltage of this LTM8067.
Maybe there is some characteristic of LTM8067 I've missed out that can cause such problems?
