LTC3859AHUHF#PBF Overview
With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 3 numbers. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. 4.5V~38V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. The switching controller is capable of switching at the 115kHz~835kHz 350kHz~535kHz position. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . There are many different types of terminations for 38. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Searching "LTC3859" will return other relevant dc to dc converter ics. Switching converter is a type of Switching Regulator or Controllers in particular. The minimum input voltage of the dc dc voltage regulator should be 4.5V. DC regulator outputs 5.4V voltage according to the test statistics.
