The Future of Analog IC Technology
MP3910A
Peak Current Mode Boost PWM Controller
with Programmable Frequency, External Soft Start
Light Load Operation, and SOIC8 Package
DESCRIPTION
The MP3910A 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 400µA and
can accommodate flyback, boost for non-
isolated and isolated applications.
Current mode control provides inherently simple
loop compensation and cycle-by-cycle current
limit. Under-voltage lockout, soft-start and slope
compensation are all provided to minimize the
external component count.
While designed for Flyback applications, the
MP3910A 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, MP3910A 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 MP3910A is available in SOIC8 package.
