FEATURES  
DESCRIPTIO  
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 VCESAT  
switchallowingasmallconverterfootprintandlowerparts  
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.  
Integrated Schottky Rectifier  
Fixed Frequency 1.2MHz/2.7MHz Operation  
Very Low Noise: 1mVP-P Output Ripple  
Low VCESAT Switch: 270mV at 250mA  
–5V at 100mA from 5V Input  
–12V at 30mA from 3.3V Input  
Low Input Bias Current GND Based FB Input  
Low Impedance (40) 1.265V Reference Output  
The LT3462/LT3462A operate in a dual inductor inverting  
topology that filters both the input and output currents.  
Verylowoutputvoltagerippleapproaching1mVP-P canbe  
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 VIN to VOUT differential of  
up to 38V for dual inductor topologies.  
High Output Voltage: Up to 38V  
Wide Input Range: 2.5V to 16V  
Uses Tiny Surface Mount Components  
Low Shutdown Current: <10µA  
Low Profile (1mm) SOT-23 (ThinSOTTM) Package

APPLICATIO S  
Both devices provide a low impedance 1.265V reference  
output to supply the feedback resistor network. A ground
