... Dynamic transitioning between internal VID settings and the external divider is not allowed. Input and Output Capacitors The input capacitance requirement is as follows: EP5352Q, EP5362Q = 2.2uF EP5382Q = 4.7uF Enpirion recommends that a low ESR MLCC capacitor be used. The input capacitor must use a X5R or X7R or equivalent dielectric © ...
