LTC3859AIFE#PBF Overview
It comes in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 3 numbers. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 4.5V~38V voltage are supplied and operated. A -40°C~125°C TJ dc switcher is not a problem. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Various 38 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Search for "LTC3859" to find other relevant dc to dc converter ics. Pins number 38 of switching converter in total. Specifically, switching converter falls under the Switching Regulator or Controllers category. dc dc voltage regulators should have a minimum input voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.4V. In most cases, the output current of the dc dc regulator will be 25A, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. DC regulator's maximum frequency is 850kHz.
