LTC3859AEUHF#PBF Product Details

LTC3859AEUHF#PBF Overview


It comes in the 38-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. For outputs of 3, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 4.5V~38V. Suitable for a -40°C~125°C TJ dc switcher. The switching controller can be switched at 115kHz~835kHz 350kHz~535kHz. A generalization of dc dc regulator can be made using Surface Mount. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position QUAD . 38 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". Pins number 38 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, the DC regulator outputs 5.4V voltage. normally, the dc dc regulator's output current is 25A, which you should keep in mind when starting a project. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. There is a maximum frequency of 850kHz for this dc regulators.
