PIN FUNCTIONS
Pin # Name Description
1
COMP Compensation Pin. Connect a capacitor and resistor in series to ground for loop stability.
2
FB
Feedback Input. Reference voltage is 1.25V. Connect a resistor divider to this pin.
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
GND Ground. The exposed pad is connected to GND.
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
IN
Input Supply Pin. IN must be locally bypassed.
Frequency Select Pin. Tie to IN (through a 100k
resistor if V
IN
> 6V) for 1.3MHz operation or to
GND for 700KHz operation.
Soft-Start Control Pin. Connect a soft-start capacitor to this pin. The soft-start capacitor is
charged with a constant current of 6μA. Leave SS disconnected if the soft-start is not used.

OPERATION
The MP3213 uses a constant frequency, peak
current mode boost regulation architecture to
regulate the feedback voltage.
The operation of the MP3213 can be
understood by referring to the block diagram of
Figure 1.
