LT3462/LT3462A  
Inverting 1.2MHz/2.7MHz  
DC/DC Converters with  
Integrated Schottky  
DESCRIPTION  
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  
switch allowing a small converter footprint and lCoEwSAeTr  
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.

Low Shutdown Current: <10µA  
Very low output voltage ripple approaching 1mV can

up to 38V for dual inductor topologies.  
APPLICATIONS  
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.
