LTC3879IUD#TRPBF Overview
Capsuled in the 16-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tape & Reel (TR) solid enclosure protects the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4V~38V. Qualified to work in an dc switcher with -40°C~85°C TA. Surface Mount makes it suitable for general dc dc regulator. Enable, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. A variety of 16 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE FREQUENCY MODULATION. A DC switcher's nominal voltage of 15V is input. Search for "LTC3879" to find other relevant dc to dc converter ics. There are only 16 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 34.2V voltage based on test statistics. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. In most cases, the output current of the dc dc regulator will be 25A, so note that when you start the project. The max frequency of the pmic can reach 2MHz.
