advertisement SOT-23 DC/DC Converters Generate Up to В±35V Outputs and
Consume Only 20ВµA of Quiescent Current вЂ“ Design Note 223
Bryan Legates
TodayвЂ™s portable devices need small power supply solutions that operate with a minimum of supply current.
To meet these needs, Linear Technology introduces the
LTВ®1615, LT1615-1, LT1617 and LT1617-1 micropower
SOT-23 DC/DC converters. With an input voltage range
as low as 1V and an output voltage range as high as
В±35V, these devices provide considerable power supply
design п¬‚exibility.
The LT1615 and LT1615-1 are designed to regulate
positive output voltages, whereas the LT1617 and
LT1617-1 are designed to directly regulate negative output voltages without the need for feedback
level-shifting circuitry. The LT1615 and LT1617 have a
350mA current limit and a minimum input voltage of
1.2V, whereas the LT1615-1 and LT1617-1 have a lower,
100mA current limit and a minimum input voltage of
1V. All four converters use tiny, low proп¬Ѓle inductors
and capacitors to minimize the overall system footprint
and cost. With a quiescent current of only 20ОјA and
a shutdown current of 0.5ОјA, these devices squeeze
the most life out of any battery-powered application. В±20V Dual-Output Converter

Switching Regulators Extend Battery
Life in Space-Sensitive Applications
by Bryan Legates
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. …
