LTC3859AMPFE#PBF Overview

It comes in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. 3 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. 4.5V~38V is the supply voltage and the operating voltage of the dc control. A -55°C~150°C TJ dc switcher is not a problem. Using this switching controller, it is possible to switch at 115kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. The switching converters's terminals (s) are designed at DUAL. A variety of 38 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. You can find other relevant dc to dc converter ics by searching "LTC3859". Specifically, switching converter falls under the Switching Regulator or Controllers category. dc dc voltage regulators should have a minimum input voltage of 4.5V. DC regulator outputs 5.4V voltage according to the test statistics.
