TL3845DRG4 Overview


In the SOIC package, the switching controller meets most application requirements. There is a Tape & Reel (TR) solid enclosure around the pmic. In this switching controller, the switch can be set to 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. The 14 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Total pins of switching converter are 14. Specifically, switching converter falls under the Switching Regulator or Controllers category. The maximum duty cycle of this voltage regulator dc to dc is set to 48 % to ensure reliability during power-up and power-down. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controllers work at 500kHz Hz. Ideally, dc regulator should be kept at a temperature of 0°C or higher. Running the machine at 70°C is ideal. Total number of functions (s) for thare switch converters are 1. Voltage regulators switching is designed with 14 pins. Switching can take place at a maximum frequency of 500kHz. It is possible to set the input voltage to 5.5V for nominal working status. Inputs of 200mA are ideal for this component. normalworking processes output 30V voltage. Switches with 1 phases are used in this controller. A maximum supply voltage of 30V is specified.
