LTC1775 - High Power No RSENSE Current Mode Synchronous Step-Down Switching Regulator

The LTC1775 is a synchronous Step-down Switching Regulator controller that drives external N-channel Power MOSFETs using few external components. Current mode control with MOSFET VDS sensing eliminates the need for a sense resistor and improves efficiency. Largely similar to the LTC1625 the LTC1775 has twice the maximum sense voltage for high current applications. The frequency of a nominal 150kHz internal Oscillator CAN be synchronized to an external Clock over a 1.5:1 frequency range. Burst Mode operation at low load currents reduces switching losses and low dropout operation extends operating time in battery-powered systems. A forced continuous mode control pin CAN assist secondary winding regulation by disabling Burst Mode operation when the main output is lightly loaded. Fault protection is provided by foldback current limiting and an output overvoltage Comparator An external capacitor attached to the RUN/SS pin provides soft start capability for supply sequencing. A wide supply range allows operation from 4V (4.3V for LTC1775I) to 36V at the input and 1.19V to VIN at the output.
