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 l^Co^Ew^SAe^Tr

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.

FEATURES

Integrated Schottky Rectifier

Fixed Frequency 1.2MHz/2.7MHz Operation

Very Low Noise: 1mV Output Ripple

P-P

Low V

Switch: 270mV at 250mA

CESAT

–5V at 100mA from 5V Input

–12V at 30mA from 3.3V Input

Low Input Bias Current GND Based FB Input

Low Impedance (40Ω) 1.265V Reference Output

High Output Voltage: Up to –38V

Wide Input Range: 2.5V to 16V

The LT3462/LT3462A operate in a dual inductor inverting

topology that filters both the input and output currents.

Uses Tiny Surface Mount Components

Low Shutdown Current: <10µA

Very low output voltage ripple approaching 1mV can

be achieved when ceramic capacitors are used. Fixed fre‑

quency switching ensures a clean output free from low

tions. The 40V switch allows a V to V

differential of

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.
