SGM66056
Tiny, 2.2MHz, Fixed Output Synchronous
Step-Up Converter with a 2.5A Switch
GENERAL DESCRIPTION
The SGM66056 is an internally compensated, 2.2MHz
switching frequency, current mode, synchronous
step-up (boost) switching regulator. This device turns
into power-save mode to maintain high efficiency by
lowering switching frequency. Anti-ringing control
circuitry reduces EMI concerns by damping the inductor
in discontinuous mode. Its output is disconnected by
the rectifier circuit during shutdown, with no input to
output leakage.
The SGM66056 is available in a Green WLCSP-
1.21×1.21-9B package. It operates over an ambient
temperature range of -40to +85.
FEATURES
93% Efficiency Synchronous Boost Converter
Device Quiescent Current: 34µA (TYP)
Less than 1µA Shutdown Current
Operating Input Voltage Range: 2.5V to 4.5V
Fixed Output Voltage: 5.0V
Output Voltage Clamping: 5.7V
Power-Save Mode for Improved Efficiency at
Low Output Power
Load Disconnect during Shutdown
Low Reverse Leakage Current when VOUT > VIN
Over-Temperature Protection
Available in a Green WLCSP-1.21×1.21-9B Package

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 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, or specifications without prior notice.
