LT3460/LT3460-1

1.3 MHz/650kHz Step-Up

DC/DC Converter in SC70,

ThinSOT and DFN

FEATURES

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.

1.3MHz (LT3460) Switching Frequency

650kHz (LT3460-1) Switching Frequency

High Output Voltage: Up to 36V

300mA Integrated Switch (LT3460)

180mA Integrated Switch (LT3460-1)

Wide Input Range: 2.5V to 16V

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.

Uses Small Surface Mount Components

Low Shutdown Current: <1μA

Low Proﬁle (1mm) SC70 (LT3460 and LT3460-1),

SOT-23 (ThinSOT™) (LT3460) and 2mm × 2mm DFN

(LT3460-1) Packages

The low 1mA quiescent current and 650kHz switching

frequency of LT3460-1 make it ideal for lower current

applications.

APPLICATIONS

Digital Cameras

The LT3460 is available in SC70 and SOT-23 packages.

The LT3460-1 is available in SC70 and 2mm × 2mm DFN

packages.
