The LTM8064 is a 58VIN, 6A, constant-voltage, constantcurrent (CVCC), step-down μModule® (power module) regulator. Included in the package are the switching controller, 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, compact (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.

Demonstration circuit 2237A is a 58VIN, 6A, CVCC StepDown μModule® Regulator featuring the LTM8064. The demo circuit is designed for a 5V output from an input voltage range of 7.5V to 58V. The output can source 7A (typical) or sink 9.1A (typical). The circuit can be operated in either constant voltage mode or constant current mode. Two or more LTM8064s can be paralleled to share load current equally. In this configuration, a master part determines the output currents of the slave parts. The MODE pin of the master part should be floating and all MODE pins of slave parts should be grounded. When the output sinks current, the circuit maintains its output voltage regulation by power conversion, not power dissipation. This means that the energy provided to LTM8064 is in turn delivered to its input power bus. There must be something on the input power bus to accept or use the energy. The LTM8064 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 2237A.
