LTC3850IUFD#TRPBF Overview
Capsuled in the 28-WFQFN Exposed Pad package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 2 input. An enclosure of Tape & Reel (TR) is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 4V~30V. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 250kHz~780kHz. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at QUAD . A variety of dc switching's functions can be performed on 28 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. LTC3850 can be used to locate other relevant dc to dc converter ics. 28 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator must be 4V. According to the test statistics, DC regulator outputs 23.32V voltage. The dc to dc regulator is limited to 30V input voltage. DC regulator's maximum frequency is 860kHz. A high-quality communication requires 1 channels.
