LTC3859IFE#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. 3 outputs can be generated with the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 4.5V~38V. Work well in dc switchers with a -40°C~125°C TJ. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. An array of 38 terminations of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. LTC3859 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 38 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. The minimum input voltage of the dc dc voltage regulator should be 4.5V. The test statistics indicate that DC regulator outputs a voltage of 60V. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. A high-quality communication requires 1 channels.
