MVPG30x/MVPG31
1 MHz, 3.0A Peak Current-Limit Step-Down Regulator
with AnyVoltage™ Technology
Datasheet
PRODUCT OVERVIEW
The Marvell
®
MVPG30x/MVPG31 is an intelligent digital
synchronous step-down (Buck) switching regulator
housed in a 4 mm x 3 mm DFN-12 package. The
MVPG15x has an additional on-chip Low-Drop-Out
(LDO) regulator controller. Internally self-compensated,
the step-down regulator requires no external
compensation and work with low-ESR output capacitors
to simplify the design, minimize the board space, and
reduce the amount of external components. The
switching frequency for the step-down regulator is
1 MHz, allowing the use of low profile surface mount
inductors and low value capacitors. The step-down
regulator includes programmable output voltage to
provide the user the ability to easily set the output
voltage with external resistors, logic control, or serial
data interface. The output voltage range is 0.72V to
3.63V.
The LDO regulator controller with an external P-Channel
MOSFET forms a low dropout regulator capable of
driving 800 mA output current. The output voltage of the
LDO regulator is fixed.
The MVPG30x/MVPG31 operate from an input voltage
range of 3.0V to 5.5V, making the device well-suited for
portable applications.
Other key features of the MVPG30x/MVPG31 include an
internal current limit for the step-down regulator, an
Under Voltage Lockout (UVLO), and thermal shutdown.
