LTC3850IGN-1#PBF Overview


It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 2 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds 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. This switching controller can switch at 250kHz~780kHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . Various 28 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "LTC3850" will return other relevant dc to dc converter ics. Total pins of switching converter are 28. Switching converter type is specifically 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 can only accept a maximum input voltage of 30V. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. The max frequency of the pmic can reach 860kHz. Channels are 1 for high-quality communication.
