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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T
J
(MAX)-
T
A
)/
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4-layer board.
