LT3460/LT3460-1
1.3 MHz/650kHz Step-Up
DC/DC Converter in SC70,
ThinSOT and DFN
DESCRIPTION
The LT
®
3460/LT3460-1 are general purpose step-up DC/
DC converters. The LT3460/LT3460-1 switch at 1.3MHz/
650kHz, allowing the use of tiny, low cost and low height
capacitors and inductors. The constant frequency results
in low, predictable output noise that is easy to filter.
The high voltage switches in the LT3460/LT3460-1 are
rated at 38V, making the device ideal for boost converters
up to 36V. The LT3460 can generate 12V at up to 70mA
from a 5V supply.
The low 1mA quiescent current and 650kHz switching
frequency of LT3460-1 make it ideal for lower current
applications.
The LT3460 is available in SC70 and SOT-23 packages.
The LT3460-1 is available in SC70 and 2mm × 2mm DFN
packages.
