LTC3859EUHF#PBF Product Details

LTC3859EUHF#PBF Overview


As a result of 38-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 3 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4.5V~38V is the supply voltage and the operating 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 can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at QUAD. There are many different types of terminations for 38. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3859" will reveal other relevant dc to dc converter ics. 38 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator must be 4.5V. Statistically, the DC regulator outputs 60V voltage. It's important to remember that the dc dc regulator's normaloutput current is 25A, so you should note it down when starting a new project. DC regulators have a maximum frequency of 850kHz. Channels 1 are required for high-quality communication.
