High precision constant voltage and current regulation at universal AC input.
Programmable CV and CC regulation.
Integrated power MOSFET.
Good dynamic response.
Programmable Brownout Protection and Line OVP Protection(For 2571Lx only).
Built-in line compensation for tight CC regulation.
Built-in fixed cable compensation.
Built-in primary winding inductance compens.
