LTC3850EGN-1#PBF Overview
With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 2 output generation. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 4V~24V. Suitable for working in an dc switcher that has a -40°C~85°C TA. It can switch at 250kHz~780kHz. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 28 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3850". In total, switching converter has 28 pins. Switching converter type is specifically Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 23.32V. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. The max frequency of the pmic can reach 860kHz. Channels 1 are required for high-quality communication.
