Description

EV3910A-S-00A Evaluation Board is designed to demonstrate the capabilities of MP3910A. MP3910A is a Peak Current Mode PWM controller that can drives an external MOSFET capable of handling >10A current. It has a typical operational current of 400μA and can accommodate flyback, boost for nonisolated and isolated applications.While designed for Boost 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, MP3910A has pulse skipping Mode function that improves the efficiency with light load or no load.The MP3910A is available in SOIC8 package
