LTM8064 - 58VIN, 6A CVCC Step-

Typical Application

Description

The LTM®8064 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.

Applications

  • Short- Circuit Protection or Accurate Output Current Limit
  • High Power LED Drive
  • Peltier Driver
  • Motor Drive
  • Battery/Supercap Charging and Cell Balancing
