Analog Devices LTM4678 Regulator | DigiKey Daily
Analog Devices' LTM4678 is a dual 25 amp or single 50 amp step-down power module DC-to-DC regulator. It’s comprised of digitally programmable analog control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors, and supporting components. Its 2-wire serial interface allows outputs to be margined, tuned, and ramped up and down at programmable slew rates with sequencing delay times. At start-up, parameters such as output voltages, switching frequency, and channel phase angle assignments can be set by pin-strapping resistors. It has an input voltage range from 4.5 volts to 16 volts, produces output voltages between 0.5 volts and 3.3 volts, and can operate between minus 40 degrees Celsius and 125 degrees Celsius. It’s ideally suited for data mining and system optimization applications.
