LTC3861IUH-1#PBF Overview


Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. PMIC packaging is solid with a Tube enclosure. With this function, you can deal with PWM Signal dc switching's outputs (s). A 3V~5.5V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. In this switching controller, the switch can be set to 250kHz~3MHz. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at QUAD . A variety of dc switching's functions can be performed on 32 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. In addition to "LTC3861", there are other relevant dc to dc converter ics you can find. 32 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Based on the test statistics, DC regulator outputs voltage 5.5V. You should note down the dc dc regulator's usual output current of 60A when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 91.5 %. Switching controllers operate at 2.25MHz frequencies. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. Input voltage can be set to 24V for nominal working status.
