MPM3830
6V Input, 3A Module
Synchronous Step-Down Converter
with Integrated Inductor
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MPM3830 is
a
step-down module
•
•
•
•
•
Wide 2.7V to 6V Operating Input Range
Adjustable Output from 0.6V
converter with built-in power MOSFETs and
inductor. The DC-DC module comes in a small
surface-mount QFN-20(3mm x 5mm x 1.6mm)
package and achieves 3A continuous output
current from a 2.7V to 6V input voltage with
excellent load and line regulation. The
MPM3830 is ideal for powering portable
equipment that runs from a single cell Lithium-
Ion (Li+) Battery. The output voltage is
regulated as low as 0.6V. Only FB resistors and
input and output capacitors are needed to
complete the design.
3.0mm x 5.0mm x 1.6mm QFN Package
Total Solution Size 8.5mm x 4.5 mm
Low Radiated Emissions (EMI) Complies
with EN55022 Class B Standard
Up to 3A Continuous Output Current
100% Duty Cycle in Dropout

Ultra Low IQ: 40μA
EN and Power Good for Power Sequencing
Cycle-by-Cycle Over-Current Protection
Short-Circuit Protection with Hiccup Mode
Adjustable Output Only Needs 4 External
Components : 2 Ceramic Capacitors and FB
Divider Resistors
The Constant-on-time control (COT) scheme
provides fast transient response, high light-load
efficiency and easy loop stabilization.
APPLICATIONS
Fault condition protection includes cycle-by-cycle
current limit and thermal shutdown (TSD).

Low Voltage I/O System Power
LDO Replacement
Power for Portable Products
Storage (SSD/HDD)
The MPM3830 requires a minimum number of
readily available standard external components
and is available in an ultra-small QFN20
(3mmx5mm) package.
