TL3843P Overview


Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 1 input. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 7.6V~30V voltage are supplied and operated. Qualified to work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to Up to 500kHz. The Through Hole value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING REGULATOR analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. In addition to "TL3843", there are other relevant dc to dc converter ics you can find. There are a total of 8 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. A 30V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. There is 500kHz frequency setting on the switching controller. In a dormant state, the dc switching uses 11mA. 5.5V is the nominal working voltage. Switching controller is necessary to provide a voltage of 15V. You should not supply more current than 30mA to the controller.
