LTC3859ALEFE#PBF Overview


Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller can be used for a wide range of applications. dc motor controller is suitable for 3 output generation. A solid enclosure of Tube surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. 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. It can switch at 115kHz~835kHz 350kHz~535kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 38 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 12V. Searching "LTC3859" will return other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V.
