SGM3110
Micro-Power Regulated Charge Pump
GENERAL DESCRIPTION
FEATURES
The SGM3110 is a Micro-Power switched capacitor
● Step-Up Voltage Converter
voltage converter that delivers a regulated output. No
● Input Voltage Range:
SGM3110-5.0: 2.7V to 5.0V
external inductor is required for operation.
The SGM3110 can deliver up to 100mA to the voltage
regulated output. It features very low quiescent current
and high efficiency over a large portion of its load range,
making
this
device
ideal
for
battery-powered
applications. Furthermore, the combination of few
external components and small package size keeps the
total converter board area to a minimum in spacerestricted applications.
The SGM3110 uses a pulse skipping technique to
provide a regulated output from a varying input supply.
The SGM3110 contains a thermal management circuit
to protect the device under continuous output shortcircuit conditions.
The SGM3110 is available in Green SOT-23-6 package
and is rated over the -40℃ to +85℃ temperature
range.
SGM3110-4.5: 2.7V to 4.5V
● Micro-Power Consumption: 60µA
● 4.5V and 5V Regulated ±4% Output Voltages
● 250mA Peak Current for 100ms
● High Frequency 750kHz Operation
● Logic-Controlled Shutdown
● Short-Circuit and Over-Temperature Protections
● Available in Green SOT-23-6 Package

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.
