LTC3850EUF#PBF Overview


Capsuled in the 28-WFQFN Exposed Pad package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 2 numbers. PMIC is packaged in a solid enclosure of Tube. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 4V~24V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~85°C TA. With this switching controller, you can switch at 250kHz~780kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. QUAD are the position of the terminal of the switching converters. 28 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "LTC3850". In particular, switching converter is a type of Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. Statistically, the DC regulator outputs 5V voltage. Whenever the current value is 0.1A, switching converter outputs the highest possible value.
