Input Reflected Ripple Current Test Step

Input reflected ripple current is measured through

a source inductor Lin(12uH) and a source capacitor

and full load.

Output Voltage Tolerance Envelope Curve

The voltage tolerance envelope shows typical load

regulation characteristics for this product series.

The tolerance envelope is the maximum output

voltage variation due to changes in output loading.

Output Ripple & Noise Measurement Test

Use a capacitor Cout(0.1uF) measurement.

The Scope measurement bandwidth is 0-20MHz.

EMI Filter

Input filter components (C1, L ) are used to help

meet conducted emiS10A1Tions requirement for the

module.

These components should be mounted as close as

poS10A1Tible to the module; and all leads should be

minimized to decrease radiated noise.
