SGM6021
Programmable Output Voltage Ultra-Low Power
Step-Down Converters with Up to 200mA Output Current
GENERAL DESCRIPTION
The SGM6021 family provides a highly integrated
ultra-low power step-down converter solution that is
well suited for meeting the special needs of ultra-low
power applications such as energy harvesting. The
SGM6021 family provides the system with an externally
programmable regulated supply to preserve the overall
efficiency of the power-management stage compared
to a linear step-down converter. The regulators are
intended to step-down the voltage from an energy
storage element such as a battery or super capacitor to
supply the rail to low-voltage electronics. The regulated
output has been optimized to provide high efficiency
across low output currents (<10μA) to high currents
(200mA).
The SGM6021 family integrates an optimized hysteretic
controller for low-power applications. The internal
circuitry uses a time-based sampling system to reduce
the average quiescent current.
The output regulator levels are programmed through
VS pin.
All the capabilities of SGM6021 are packed into a small
UTDFN-1.5×2-6L 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.
