MP3910GK-Z

The MP3910 is a Peak Current Mode PWM
controller that can drive an external MOSFET
capable of handling more than 10A current. It
has a typical operational current of 288µA and
can accommodate flyback, boost for nonisolated and isolated applications.
Current mode control provides inherently simple
loop compensation and cycle-by-cycle current
limit. Under-voltage lockout, soft-start, internal
regulated supply and slope compensation are
all provided to minimize the external component
count.
While designed for Flyback applications, the
MP3910 can also be used for other topologies
including Boost, Forward and Sepic. 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.
