... CUI INC MODEL: NDM1-25-120 OPERATING INFORMATION - POWER MANAGEMENT INPUT FILTERING The NDM1-25 module has built-in capacitances to supply the pulsed current due to PWM switching. However, to help minimize input voltage ripples, additional input capacitance is recommended as follows: 1x 330μF POSCAP or electrolytic and 3x 22μF ceramic capacitors, placed as close as possible to the input pins ...
