DESCRIPTION:

The LTM®8064 is a 58VIN, 6A, constant-voltage, constantcurrent (CVCC), step-down µModule® (micromodule)regulator. Included in the package is the switching controller, the power switches, an inductor and the supportedcomponents. Operating over an input voltage range of 6Vto 58V, the LTM8064 supports an output voltage rangeof 1.2V to 36V. The CVCC operation allows the LTM8064to accurately regulate its output current up to 7A whensourcing and 9.1A when sinking over the entire outputrange. The output current can be set by a control voltage,a single resistor, or a thermistor. To set the switching frequency, simply place a resistor from the RT pin to ground.A resistor from FB to ground will set the output voltage.Only bulk input and output filter capacitors are needed tofinish the design.The LTM8064 is packaged in a thermally enhanced, compact (16mm × 11.9mm × 4.92mm) over-molded ball gridarray (BGA) package suitable for automated assemblyby standard surface mount equipment. The LTM8064 isRoHS compliant.
