UC3843ADTRG4 Product Details
UC3843ADTRG4 Overview
With its SOIC package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. In this switching controller, the switch can be set to 500kHz. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 14 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. 14 pins are on switching converter. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Switching controllers work at 450kHz Hz. Temperatures should be kept at 0°C or higher. There should be 70°C more than 70°C degrees Celsius in the machine. Total number of functions (s) for thare switch converters are 1. There is a design for voltage regulators switching with 14 pins. Maximum frequency of the controller is 500kHz. A nominal working status is achieved when the input voltage is set to 25V. Input values of 200mA make it ideal for switching controllers. normalworking processes output 15V voltage. There is a requirement for a 11V supply voltage. Maximum supply voltage is 30V.
