LTC3859IFE#PBF Overview
It comes in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. 3 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. Switching can be done at 115kHz~835kHz 350kHz~535kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. Various 38 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. There are a total of 38 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. Statistically, the DC regulator outputs 60V voltage. There is a maximum frequency of 850kHz for this dc regulators. Channels 1 are required for high-quality communication.
