LTC3851EMSE#PBF Overview
In the 16-TFSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. Tube solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 4V~38V. Suitable for work in a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 250kHz~750kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 16 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics can be found by searching "LTC3851". 16 pins are on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. According to the test statistics, DC regulator outputs 800mV voltage. It's important to remember that the dc dc regulator's normaloutput current is 50mA, so you should note it down when starting a new project. Switching controller operates at 750kHz Hz. A circuit should contain 15V in order to ensure the voltage regulator dc to dc runs safely and reliably. The maximum input voltage of this dc switcher is 38V, so users must limit the voltage accordingly. DC switchers cannot produce output currents greater than 25A. Depending on the datasheet, the switching converter can output 5.5V volts at its peak. The voltage controller's lowest voltage output is not less than 800mV.
