AC DC Flyback Converters

MPS provides MOSFET integrated flyback converters to simplify circuit design for 30W and below applications, and also provides flyback controller solutions for higher power applications. Our product family is divided into 2 sub-families: primary side regulation flyback and secondary side regulation flyback. Primary side regulation flyback can save the opto-coupler and secondary feedback unit, which largely reduces the components number and solution size. Secondary side regulation flyback provides higher regulation accuracy and faster transient response, which is important for chargers and other applications.

Choose between primary regulation flybacks or secondary regulation flybacks

Primary regulation flybacks use the transformer winding to sense output voltage, so it does not need optocoupler and a secondary voltage sense circuit, largely reducing the component number and shrinking the solution size. But the drawback is regulation will not be as good as secondary regulation due to transfomer coupling, and secondary diode dropout voltage leading to the difference of output voltage and sense voltage. Primary regulation dynamic performance is also worse than secondary regulation. Usually primary regulation is used in low power(<10W) application without high accuracy requirement; for higher power applications, usually secondary regulation is more popular.

Find the right Flyback Converter solution

If you are looking for a compact flyback solution, the MPX2001 all-in-one flyback controller may be an excellent choice with Integrated Primary and Secondary, Synchronous Rectification Driver by Capacitive Isolation.

MPS has the leading secondary synchronous rectifier technology. Regulation output ensures fast turn off speed and avoids secondary FET still being turned on when primary FET is turned on, making it possible to be used in CCM mode. The MP6908 has wide input voltage range which allows customers to use single winding , and it’s perfect for USB PD or Quick charger applications. MPS's unique control scheme achieves the best efficiency in the minimum solution size. MPS has different secondary rectifiers to fit into flyback, LLC topology, and are widely used in chargers and adapters.
