Notes:
1. Ripple & noise measured with 20 MHz bandwidth.
2. Tested by minimal Vin and constant resistive from 2 % to 100 % load.
3. Tested by normal Vin and 25 % load step change ( 75 %-50 %-25 % of full output load ).
4. Input reflected ripple current is measured through a source inductor L1: 12 µH and a source capacitor C1: 47 µF
5. Do not operate the converter exceeding the absolute maximum rating, over rating causes damage to the units.
6. Input filter components (C1, C2, L1) are used to help meet EMI & EMS requirement for the module. See EMC filter circuit.
These components should be mounted as close as possible to the module and all leads should be minimized to decrease radiated
noise.
7. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
