Application Examples (2)
• External Synchronization with Primary-Control AC/DC Converter
This is one example of a circuit that uses the features of the HA16114/120 by operating in
synchronization with a flyback AC/DC converter. Note the following design points concerning the
circuit from the secondary side of the transformer to the
