LTC3859ALEUHF#PBF Product Details
LTC3859ALEUHF#PBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 3 input. Packaged in solid enclosures, this pmic has a Tube rating. The program can handle Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Worked in an dc switcher with a -40°C~125°C TJ rating. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. dc dc regulator can be generalized using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at QUAD . An array of 38 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. In total, switching converter has 38 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability.
