SGM66052
Efficient Synchronous Step-Up Converter
with a 2.7A Switch in UTDFN Package
GENERAL DESCRIPTION
The SGM66052 is an internally compensated, 1.1MHz
switching frequency, current mode, synchronous step-
up switching regulator, which is capable of generating
5V output at 1A load current from a 3.3V rail.
This device turns into power-saving mode to maintain
high efficiency by lowering switching frequency. With its
anti-ringing circuitry damping the charge in parasitic
capacitor, it reduces EMI interference significantly. Its
output is disconnected by the rectifier circuit during
shutdown, with no input to output leakage.
The SGM66052-5.1 is preset for outputting 5.1V, while
the SGM66052-ADJ is output voltage programmable
with an external resistor divider.
The device is available in the Green UTDFN-2×1.5-6L
package and 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.
