TL3843DRG4 Product Details
TL3843DRG4 Overview
This switching controller fits most application requirements since it is packaged in a SOIC package. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There is a switch at 500kHz that can be used with this controller. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 14 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 15V. There are only 14 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. voltage regulator dc to dcs with a 97 % duty cycle are designed to be reliable when powered on and powered off. Switching controllers operate at 500kHz frequencies. A temperature of 0°C or higher is recommended. A temperature of 70°C degrees Celsius is recommended. A total of 1 functions are present in the switch converters. It is planned to design voltage regulators switchings with 14 pins. A maximum frequency of 500kHz can be set by the controller. It is possible to set the input voltage to 5.5V for nominal working status. With 200mA input, it is ideal for switching controllers. In normal operation, it outputs 30V. Switches with 1 phases are used in this controller. As far as maximum supply voltage is concerned, switching voltage regulators is rated as 30V.
