LTC3859AEUHF#TRPBF Product Details

LTC3859AEUHF#TRPBF Overview


It comes in a 38-WFQFN Exposed Pad package, so switching controller can be used for most applications. dc motor controller is suitable for 3 output generation. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. A 4.5V~38V voltage is supplied to the dc control and used for operating it. A -40°C~125°C TJ dc switcher is not a problem. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. dc dc regulator is made easier with Surface Mount. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the QUAD position. The 38 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. LTC3859 can be used to locate other relevant dc to dc converter ics. In particular, 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. The test statistics indicate that DC regulator outputs a voltage of 5.4V.
