LTC3859EFE#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. It is sufficient to generate 3 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. The switching controller is capable of switching at the 115kHz~835kHz 350kHz~535kHz position. dc dc regulators can be carried out with Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . An array of 38 terminations of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". 38 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. Based on the test statistics, DC regulator outputs voltage 60V. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. There is a maximum frequency of 850kHz on this dc regulators. Channels 1 are required for high-quality communication.
