WARNINGS:
Insufficient heat dissipation = burning! Output >15W must be installed with heat sink (size ≤24×15mm).
High-voltage differential output is strictly prohibited: Setting voltage should be ≥ input voltage +2V (e.g. input 5V→output ≥7V).
The quality of the input power supply determines the ripple: poor quality power supply leads to ripple soaring 100% +!
