LTC3459
10V Micropower
Synchronous Boost Converter
FEATURES DESCRIPTION n The LTC®3459 is a low current, high efficiency synchronous
boost converter intended for low power, size constrained
portable applications. The LTC3459 can be powered from
a single lithium ion battery, a 2-to 3-cell stack of alkaline
or nickel batteries, or any low impedance voltage source
between 1.5V and 5.5V. The output is programmable via
an external divider between 2.5V and 10V. Although the
part is primarily intended for boost applications, VOUT will
maintain regulation below VIN (at reduced efficiency). n Small Solution Size
