LTM8064
58VIN, 6A CVCC Step-Down
µModule Regulator
Description
The LTM®8064 is a 58VIN, 6A, constant-voltage, constant-
current (CVCC), step-down µModule® (power module)
regulator. Included in the package are the switching con-
troller, power switches, inductor and support components.
Operating over an input voltage range of 6V to 58V, the
LTM8064 supports an output voltage range of 1.2V to
36V. CVCC operation allows the LTM8064 to accurately
regulate its output current up to 7A when sourcing and
9.1A when sinking over the entire output range. 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 the bulk input
and output filter capacitors are needed to finish the design.
The LTM8064 is packaged in a thermally enhanced, com-
pact (16mm × 11.9mm × 4.92mm) over-molded ball grid
array (BGA) package suitable for automated assembly
by standard surface mount equipment. The LTM8064 is
RoHS compliant.
