LTM8064IY

LTM8064IY is a 58V input, 6A constant-voltage, constant-current (CVCC) step-down µModule® (micromodule) regulator. This module includes the switching controller, power switches, an inductor, and the necessary 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 using a control voltage, a single resistor, or a thermistor. To adjust the switching frequency, simply connect a resistor from the RT pin to ground. Applications include short-circuit protection or accurate output current limit, high-power LED drivers, Peltier drivers, motor drivers, and battery/supercapacitor charging and cell balancing.
