LTC3838IFE#PBF Overview
The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. An enclosure of Tube is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 4.5V~38V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~125°C TJ. It can switch at 200kHz~2MHz. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 38 terminations are available in dc switching. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics can be found by searching "LTC3838". 38 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator should be 4.5V. DC regulator outputs 5.5V voltage based on test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 25A. DC regulators have a maximum frequency of 2MHz. To better satisfy the need, DC to DC voltage regulator has a value of OPERATE IN ADJUSTABLE MODE FROM 0.6 TO 5.5V. The dc to dc voltage regulator is from the PolyPhase? series. Channels are 1 for high-quality communication.
