DESCRIPTION
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.
