The LT3462ES6#TRMPBF is an Inverting 1.2MHz DC/DC Converter with integrated Schottky and a low VCESAT switch allowing a small converter footprint. The LT3462 switches at 1.2MHz and operate in a dual inductor inverting topology that filters both the input and output currents. These high speeds enable the use of tiny, low cost and low height capacitors and inductors. 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 up to 38V for dual inductor topologies. This converter provides 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.
