LTC3861IUH-1#TRPBF Overview


Capsuled in the 32-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. With PWM Signal dc switching's output (s), it is able to handle it. Voltages 3V~5.5V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a -40°C~125°C TJ rating. There is a switch at 250kHz~3MHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at QUAD. A variety of terminations with 32 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. In addition to "LTC3861", there are other relevant dc to dc converter ics you can find. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 3V. A maximum voltage of 5.5V is accepted by the dc to dc regulator as an input voltage. Basically, it's a dc to dc voltage regulator from the PolyPhase? series.
