EV3910-K-00A Evaluation Board is designed to demonstrate the capabilities of MP3910. MP3910 is a Peak Current Mode PWM controller that can drives an external MOSFET capable of handling >10A current. It can accommodate flyback, boost for isolated and non-isolated applications.

While designed for Flyback applications, the 1A gate driver minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices. Additionally, MP3910 has pulse skipping Mode function that improves the efficiency with light load or no load. It also provides hiccup protection for OLP, OVP and SCP condition.

The MP3910 is available in MSOP10 package.
