LTC3859EFE Overview


As a result of 38-TFSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 3 outputs. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Qualified to work in an dc switcher with -40°C~125°C TJ. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 38 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Search for "LTC3859" to find other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.4V.
