LTC3850EUF#TRPBF 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. The pmic is packaged in Tape & Reel (TR) solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 4V~24V is the supply voltage and the operating voltage of the dc control. Suitable for a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 250kHz~780kHz. dc dc regulator can be generalized using Surface Mount. 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. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of terminations with 28 of dc switching. Some of the control techniques used by these dc dc converter ics are 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. Switching converter has a total of 28 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. The test statistics indicate that DC regulator outputs a voltage of 23.32V. The max frequency of the pmic can reach 860kHz. Communication with high quality requires 1 channels.
