Input Reflected Ripple Current Test Step
Output Ripple & Noise Measurement Test
Use a capacitor Cout(1.0uF) measurement.
The Scope measurement bandwidth is 0-20MHz.
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0© at 100KHz) at nominal input and
full load.

Output Ripple & Noise Reduction
To reduce ripple and noise, it is recommended to
use a 1uF ceramic disk capacitor and a 10uF electrolytic
capacitor to at the output.

EMI Filter
Input filter components (C1,C2,C3, L1) are used to help
meet conducted emissions requirement for the module.
These components should be mounted as close as
possible to the module; and all leads should be minimized
to decrease radiated noise.
