LTC3859EFE#TRPBF Overview


The switching controller fits in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 3 numbers. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 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. There is a switch at 115kHz~835kHz 350kHz~535kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. An array of 38 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. A search for "LTC3859" will reveal other relevant dc to dc converter ics. There are only 38 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 60V. This dc regulatorhas a max frequency of 850kHz. The number of channels available for high-quality communication is 1.
