LTC3850IUF#PBF Overview


With a 28-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. 2 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4V~30V. Work well in dc switchers with a -40°C~85°C TA. A switching controller such as this can switch at a value of 250kHz~780kHz . The Surface Mount value makes it suitable for general dc dc regulator. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at QUAD. 28 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "LTC3850", there are other relevant dc to dc converter ics you can find. There are only 28 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. According to the test statistics, DC regulator outputs 23.32V voltage. The dc to dc regulator is limited to 30V input voltage. If you start a project, note down the dc dc regulator's usual output current of 25A. This dc regulatorhas a max frequency of 860kHz. A high-quality communication requires 1 channels.
