The LTM8064IY#PBF 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 LTM8064IY#PBF supports an output voltage range of 1.2V to 36V. CVCC operation allows the LTM8064IY#PBF 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 LTM8064IY#PBF 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 LTM8064IY#PBF is RoHS compliant.
