LTC3859ALEFE Product Details

LTC3859ALEFE Overview


This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. The dc motor controller is adquate to generate for 3 outputs. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. Using this switching controller, it is possible to switch at 115kHz~835kHz 350kHz~535kHz. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . An array of 38 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 12V. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. There is a particular type of Switching Regulator or Controllers in switching converter. The minimum input voltage of the dc dc voltage regulator should be 4.5V.
