Description

General part information

LT3462 Series

The LT3462/LT3462A are general purpose fixed frequency current mode inverting DC/DC converters. Both devices feature an integrated Schottky and a low VCESATswitch 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 1mVP-Pcan be achieved when ceramic capacitors are used. Fixed frequency switching ensures a clean output free from low frequency noise typically present with charge pump solutions.The 40V switch allows a VINto VOUTdifferential ofup 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.ApplicationsCCD BiasLCD BiasGaAs FET BiasGeneral Purpose Negative Voltage Supply
