LTC3859AEFE#PBF Overview
As a result of 38-TFSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. For 3 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 4.5V~38V. Qualified to work in an dc switcher with -40°C~125°C TJ. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 38 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. Searching "LTC3859" will return other relevant dc to dc converter ics. The switching converter has a total of 38 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. The minimum input voltage of the dc dc voltage regulator should be 4.5V. Based on the test statistics, DC regulator outputs voltage 5.4V. It's important to remember that the dc dc regulator's normaloutput current is 25A, so you should note it down when starting a new project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. DC regulator has a maximum frequency of 850kHz.
