LTC3859ALIUHF#TRPBF Product Details
LTC3859ALIUHF#TRPBF Overview
The switching controller fits in the 38-WFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 3 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. A 4.5V~38V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at QUAD. 38 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3859". Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator.
