Low Profile (1mm) SOT-23 (ThinSOT

) Package

The LT

3462/LT3462A are general purpose fixed fre-

quency current mode inverting DC/DC converters. Both

devices feature an integrated Schottky and a low V

CESAT

switch allowing a small converter footprint and lower parts

cost. The LT3462 switches at 1.2MHz while the LT3462A

switches at 2.7MHz. These high speeds enable the use of

tiny, low cost and low height capacitors and inductors.

The LT3462/LT3462A operate in a dual inductor inverting

topology that filters both the input and output currents.

Very low output voltage ripple approaching 1mV

P-P

can be

achieved when ceramic capacitors are used. Fixed fre-

quency switching ensures a clean output free from low

frequency noise typically present with charge pump solu-

tions. The 40V switch allows a V

to V

OUT

differential of

up to 38V for dual inductor topologies.

Both devices provide a low impedance 1.265V reference

output to supply the feedback resistor network. A ground

referenced, high impedance FB input allows high feedback

resistor values without compromising output accuracy.

The LT3462/LT3462A are available in a 6-lead SOT-23

package.
