LTC3859AMPUHF#TRPBF Overview
It comes in the 38-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. For outputs of 3, this dc motor controller is suitable. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 4.5V~38V. Workable in an dc switcher where -55°C~150°C TJ is the -55°C~150°C TJrm. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . A generalization of dc dc regulator can be made using Surface Mount. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at QUAD . A variety of dc switching's functions can be performed on 38 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. LTC3859 can be searched for other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. A 5.4V voltage of DC regulator was detected in the test statistics.
