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.
Test by nominal input voltage and constant resistive load.
Tested by normal Vin and 50% load step change ( 100%-50% of Io,50%-0% of Io ).
Measured Input reflected ripple current with a simulated source inductance of 12uH.
Exceeding the absolute ratings of the unit could cause damage. It is not allowed for continuous operating.

TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Input reflected ripple current is measured through
a source inductor Lin(4.7uH) and a source capacitor
Cin(47uF, ESR<1.0Ù
at 100KHz) at nominal input and
full load.
