UC2841DWG4 Product Details
UC2841DWG4 Overview
Capsuled in the SOIC 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. Using this switching controller, it is possible to switch at 500kHz. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 18 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 20V. Pins number 18 of switching converter in total. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 95 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controller operates at 450kHz Hz. The value of DC to DC voltage regulator is set at CURRENT MODE OPERATION IS ALSO POSSIBLE in order to fulfill the requirements more effectively. At least -20°C°C is recommended. At85°C, dc regulator should run. 1 functions are available in total for the switch converters. We design voltage regulators switchings with 18 pins. The controller can set a maximum frequency of 500kHz. It is possible to set the input voltage as 30V for nominal working statuses. With 400mA inputs, switching controller is ideal. It outputs a value of 40V in normaloperating procedures.
