LTC3859ALMPUHF#TRPBF Overview
In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. It is sufficient to generate 3 outputs with this dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Suitable for a -55°C~150°C TJ dc switcher. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC SWITCHING CONTROLLER is connected to the switch converters. QUAD are the position of the terminal of the switching converters. 38 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Other relevant dc to dc converter ics will be returned if you search "LTC3859". In particular, switching converter is a type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4.5V.
