LTC3850IUFD#PBF Product Details

LTC3850IUFD#PBF Overview


As a result of 28-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. For 2 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 4V~30V. Suitable for work in a -40°C~85°C TA dc switcher. Switching can be done at 250kHz~780kHz with this switching controller. dc dc regulator is made easier with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. The 28 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "LTC3850" will reveal other relevant dc to dc converter ics. Pins number 28 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4V. As determined by the test statistics, the output voltage of DC regulator is 23.32V. It should be noted that the dc to dc regulator only accepts 30V voltage as input voltage. You should note that the dc dc regulator's usual output current is 25A. There is a maximum frequency of 860kHz for this dc regulators. The number of channels available for high-quality communication is 1.
