LTC3859ALMPUHF#PBF Overview

In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 3 outputs. Packaging for the pmic consists of Tube solid enclosures. Transistor Driver dc switching's outputs (s) are supported. A 4.5V~38V voltage is supplied to the dc control and used for operating it. A -55°C~150°C TJ dc switcher is not a problem. There is a switch at 115kHz~835kHz 350kHz~535kHz that can be used with this controller. The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. A variety of dc switching's functions can be performed on 38 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V.
