UC3843ADTRG4 Overview
With a SOIC package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With this switching controller, you can switch at 500kHz. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of terminations with 14 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Pins number 14 of switching converter in total. Switching converter is a type of Switching Regulator or Controllers in particular. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. There is 450kHz frequency setting on the switching controller. You should keep dc regulator at 0°C degrees or higher. A temperature of 70°C degrees Celsius is recommended. In total, thare switch converters have 1 functions. We are designing chips that have 14 pins. 500kHz is the maximum frequency at which the controller can switch. 25V is the nominal working voltage. It is ideal for switching controllers with 200mA input. normalworking processes output 15V voltage. A supply voltage of 11V is required. Switching voltage regulators is rated 30V in terms of maximum supply voltage.
