SGM6022
6MHz, 600mA Synchronous
Step-Down Regulator

JULY 2020 – REV. A.1
GENERAL DESCRIPTION
The SGM6022 is a high-efficient step-down
switching voltage regulator, providing 600mA output
current and fixed output voltage. This device is
capable to provide an input voltage supply range of
2.5V to 5.5V. The 6MHz fixed frequency operation
allows the use of a 470nH output inductor and a
4.7μF output capacitor.
The SGM6022 also can work in power-save mode
under moderate and light load conditions through
pulse frequency modulation (PFM). The 22μA
typical quiescent current and the power-save mode
can further improve the system efficiency which can
reach a maximum of 90%. It has the excellent load
transient response capability. Its output could be
programmed to four different voltages, as well as
two different on/off delay times, making it ideal for
designing primary supplies.
The SGM6022 also
includes the features of internal soft-start, input
under-voltage lockout, thermal shutdown and
overload protection.
The SGM6022 is available in a Green TDFN-2×2-6L
package. It operates over an ambient temperature
range of -40℃ to +125℃.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure
to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section
is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure
to observe proper handling
and installation procedures
can cause damage. ESD damage can range from subtle
performance
degradation to
complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, or specifications
without prior notice.
