LTC3838EUHF-2#PBF Overview
It comes in a 38-WFQFN Exposed Pad package, so switching controller can be used for most applications. 2 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 4.5V~38V. Qualified to work in a -40°C~125°C TJ dc switcher. Switching can be done at 200kHz~2MHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. A variety of 38 terminations are available in dc switching. DC switcher's voltage input is 15V. Searching "LTC3838" will return other relevant dc to dc converter ics. 38 pins are on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. DC regulator's maximum frequency is 2MHz. Hence, OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 5.5 VOLT is used to better suit the DC to DC voltage regulator's situation. Thare are switch converters of the PolyPhase? series.
