LTC3859AHUHF#TRPBF Overview

With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 3 input. Tape & Reel (TR) solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~38V. Qualified to work in a -40°C~150°C TJ dc switcher. Using this switching controller, it is possible to switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at QUAD. There are many different types of terminations for 38. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. Specifically, switching converter falls under the Switching Regulator or Controllers category. This dc dc voltage regulator should be powered by a voltage of 4.5V. DC regulator outputs 5.4V voltage according to the test statistics.
