LT3462AES6#TRPBF

LT3462A is a general purpose fixed frequency current mode inverting DC/DC converter. It features an integrated schottky and a low VCESAT switch allowing a small converter footprint and lower parts cost. It switches at 2.7MHz. The high speed enables the use of tiny, low cost and low height capacitors and inductors. It operates in a dual inductor inverting topology that filters both the input and output currents. Very low output voltage ripple approaching 1mVP‑P can 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 VIN to VOUT differential of upto 38V for dual inductor topologies. It provides a low impedance 1.265V reference output to supply the feedback resistor network. It is used in application such as CCD bias, LCD bias, GaAs FET bias, general purpose negative voltage supply etc.
