MP3410 Datasheet, PDF (1/10 Pages) Monolithic Power Systems – 1.3A, 550kHz Synchronous Rectified Step-up Converter
The Future of Analog IC Technology
DESCRIPTION
The MP3410 is a highly efficient, synchronous,
fixed frequency, current-mode step-up converter
with output to input disconnect, inrush current
limiting and internal soft-start. It includes an error
amplifier, ramp generator, comparator, N-Channel
switch and P-Channel synchronous rectified
switch (which greatly improves efficiency). The
output disconnect feature allows the output to be
completely isolated from the input in shutdown
mode.
The 550kHz switching frequency allows for
smaller external components producing a
compact solution for a wide range of load currents.
The internal compensation and soft-start
minimizes the external component count and
limits the inrush current during startup. The
MP3410 has integrated power MOSFET which
can support up to 6V output and typical 1.3A
switch current.
The MP3410 is offered in a thin SOT23-5
package.
