LTC3859IUHF#TRPBF Overview
With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 3 input. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. 4.5V~38V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°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. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . Various 38 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. A search for "LTC3859" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 38. There is a particular type of Switching Regulator or Controllers in switching converter. 4.5V should be the minimum input voltage for the dc dc voltage regulator. According to the test statistics, DC regulator outputs 60V voltage. DC regulators have a maximum frequency of 850kHz. The number of channels available for high-quality communication is 1.
