LTC3859ALIUHF#TRPBF Overview


With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For 3 outputs, the dc motor controller is appropriate. PMIC packaging is solid with a Tape & Reel (TR) enclosure. 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. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of 38 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. LTC3859 can be searched for other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V.
