DESCRIPTION
The MP3213 is a current mode step-up
converter with a 3.5A, 0.18 internal switch to
provide a highly efficient regulator with fast
response. The MP3213 operates at 700KHz or
1.3MHz allowing for easy filtering and low noise.
An external compensation pin gives the user
flexibility in setting loop dynamics, which allows
the use of small, low-ESR ceramic output
capacitors. Soft-start results in small inrush
current and can be programmed with an
external capacitor. The MP3213 operates from
an input voltage as low as 2.5V and can
generate 12V at up to 500mA from a 5V supply.
The MP3213 includes under-voltage lockout,
current limiting and thermal overload protection
to prevent damage in the event of an output
overload. The MP3213 is available in a low
profile 8-pin MSOP and 10-pin QFN package
with exposed pad.

PIN FUNCTIONS
MSOP8
Pin #
QFN10
Pin #
Name Description
1 1 COMP
Compensation Pin. Connect a capacitor and resistor in series to ground for loop
stability.
2 2 FB Feedback Input. Reference voltage is 1.25V. Connect a resistor divider to this pin.
3 3 EN
Regulator On/Off Control Input. A high input at EN turns on the converter, and a low
input turns it off. When not used, connect EN to the input source (through a 100k
pull-up resistor if V
IN
> 6V) for automatic startup. EN cannot be left floating.
4 4 GND Ground. The exposed pad is connected to GND.
5 7 SW
Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the
power inductor and output rectifier to SW. SW can swing between GND and 25V.
6 8 IN Input Supply Pin. IN must be locally bypassed.
7 9 FSEL
Frequency Select Pin. Tie to IN (through a 100k resistor if V
IN
> 6V) for 1.3MHz
operation or to GND for 700KHz operation.
8 10 SS
Soft-Start Control Pin. Connect a soft-start capacitor to this pin. The soft-start
capacitor is charged with a constant current of 6A. Leave SS disconnected if the
soft-start is not used.
