SGM6022
6MHz, 600mA Synchronous Step-Down Regulator
GENERAL DESCRIPTION
The SGM6022 is a 6MHz, step-down switching
voltage regulator, with 600mA output current
capability, that delivers a fixed output from an input
voltage supply of 2.5V to 5.5V. Using an
architecture with synchronous rectification, the
SGM6022 is capable of delivering a peak efficiency
of 90%, while maintaining efficiency over 80% at
load currents as low as 1mA.
The regulator operates at a nominal fixed frequency
of 6MHz, which reduces the value of the external
components to as low as 470nH for the output
inductor and 4.7μF for the output capacitor.
At moderate and light loads, pulse frequency
modulation (PFM) is used to operate the device in
power-save mode with a typical quiescent current of
22μA. Even with such a low quiescent current, the
part exhibits excellent transient response during
large load swings. At higher loads, the system
automatically switches to fixed-frequency control,
operating at 6MHz. Its output could be programmed
to four different voltages, as well as two different
on/off delay times, making it ideal for designing
primary supply.
The SGM6022 is available in Green TDFN-2×2-6L
package. It operates over an ambient temperature
range of -40to +85.

OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other conditions beyond those indicated in the operational
section of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. 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 very small parametric changes could cause the
device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if necessary
without notice at any time.
