DESCRIPTIO
The LT
quency current mode step-up DC/DC converters. Both
devices feature an integrated Schottky and a low V
switch allowing a small converter footprint and lower parts
cost. The LT3461 switches at 1.3MHz while the LT3461A
switches at 3MHz. These high switching frequencies en-
able the use of tiny, low cost and low height capacitors and
inductors. The constant switching frequency results in
predictable output noise that is easy to filter, and the
inductor based topology ensures an input free from switch-
ing noise typically present with charge pump solutions.
The high voltage switch in the LT3461/LT3461A is rated at
40V making the device ideal for boost converters up to
38V.
The LT3461/LT3461A are available in a low profile (1mm)
SOT-23 package.
