One load is 25% to 100% load, the other load is 100% load, the output voltage variable rate is within
±5%.
Measured with 20MHz bandwidth and 1.0uF ceramic capacitor.
Tested by minimal Vin and constant resistive load.
Tested by normal Vin and 25% load step change ( 75%-50%-25% of Io ).
Measured Input reflected ripple current with a simulated source inductance of 12uH.
The remote on/off control pin is referenced to -Vin(pin2).
Input filter components (C1, L) 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.
8. An external filter capacitor is required if the module has to meet IEC61000-4-4 and IEC61000-4-5.
The filter capacitor Motien suggest: Nippon chemi-con KY series, 220uF/100V.
9. Exceeding the absolute ratings of the unit could cause damage.

TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0Ù
at 100KHz) at nominal input and
full load.

DESIGN&FEATURE CONFIGURATIONS
CTRL Module ON / OFF
Positive logic turns on the module during high logic
And off during low logic.
Ctrl module on/off can be controlled by an external
switch between the ctrl terminal and -Vin terminal.
The switch can be an open collector or open drain
For positive logic if the ctrl feature is not used,
please leave the ctrl pin floating.
