UC3827DW-1G4 Product Details
UC3827DW-1G4 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 3 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 24 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Pins number 24 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. Switching controller operates at 450kHz Hz. The value of DC to DC voltage regulator is set at CAN ALSO WORK IN CURRENT MODE in order to fulfill the requirements more effectively. At least 0°C°C is recommended. At70°C, dc regulator should run. 1 functions are available in total for the switch converters. We design voltage regulators switchings with 24 pins. The controller can set a maximum frequency of 500kHz. It is possible to set the input voltage as 15V for nominal working statuses. With 100mA inputs, switching controller is ideal. It outputs a value of 2.5V in normaloperating procedures. Switching controller is necessary to provide a voltage of 15V. Voltage maximum is rated 20V.
