DESIGN FEATURES SOT-23 Switching Regulators Deliver
Low Noise Outputs in a Small Footprint
by Steve Pietkiewicz
Introduction L1
4.7ВµH 100 90
EFFICIENCY (%) As portable electronics designers continue to press for reduction in
component sizes, Linear Technology
introduces the LT1611 and LT1613
SOT-23 switching regulators. These
current mode, constant frequency
devices contain internal 36V switches
capable of generating output power
in the range of 400mW to 2W, in a 5lead SOT-23 package. The LT1613
has a standard positive feedback pin
and is designed to regulate positive
voltages. The LT1611 has a novel
feedback scheme designed to directly
regulate negative output voltages
without the use of level-shifting circuitry. Boost, single-ended primary
inductance converters (SEPIC) and
inverting configurations are possible
with the LT1613 and LT1611. The
high voltage switch allows hard-todo, yet popular DC/DC converter …

Introduction L1
4.7ВµH VIN
1.5V TO 3V The LT1615 and LT1617 are pin
compatible with two other members
of the PowerSOTв„ў family, the LT1613
and LT1611, respectively. This allows
the same board layout to be used to
evaluate the performance of multiple
devices. The LT1613 and LT1611 are
both current mode, constant frequency devices, capable of producing
larger output currents than the
LT1615 and LT1617.1 LT1615 2-Cell to 3.3V
Boost Converter
A popular supply for many portable
electronic devices, a 2-cell alkaline to
3.3V converter with the LT1615 can
deliver 60mA of load current. The
circuit is shown in Figure 1 and the
system efficiency appears in Figure 2. …

DESIGN FEATURES Inverting Switching Regulator Delivers
High Current/Low Noise Outputs
in a SOT-23
by Albert Wu
Introduction
The LT1931 is the industryвЂ™s highest
power SOT-23 inverting switching
regulator. The on-chip 1A switch
allows high output currents to be
generated. In a typical 5V to вЂ“5V
application, the part can deliver
350mA; a 5V to вЂ“12V application can
provide 150mA. The LT1931 switches
at a fixed frequency of 1.2MHz, allowing the use of tiny, low cost capacitors
and inductors of 2mm or less in height.
The constant switching frequency
keeps the output voltage noise low
and predictable, making designs with
output voltage ripple less than 5mVP-P
easily achievable. An integrated shutdown feature limits the supply current
to less then 1ВµA when the part is
disabled, extending battery life. The
high power and low noise LT1931 …
