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.
