LTC3649IFE#PBF Description
The LTC3649IFE#PBF is a high-efficiency 60V, 4A synchronous monolithic step-down regulator. The regulator features a single resistor programmable
output voltage, internal compensation, and high efficiencies over a wide VOUT range. The step-down regulator operates from an input voltage
range of 3.1V to 60V and provides an adjustable rail-to-rail output range from (VIN – 0.5V) to ground while delivering up to 4A of output current.
The switching frequency is also adjusted with an external resistor.
