UC3843BVN Overview
It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. For 1 outputs, the dc motor controller is appropriate. An enclosure of Tube is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 7.6V~30V. Qualified to work in an dc switcher with -40°C~105°C TA. In this switching controller, the switch can be set to Up to 500kHz. The Through Hole allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". There are only 8 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.1V voltage. The dc to dc regulator is limited to 25V input voltage. You should note down the dc dc regulator's usual output current of 1A when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 96 %. Switching controllers work at 60kHz Hz. A circuit should contain 30V in order to ensure the voltage regulator dc to dc runs safely and reliably. Dormant dc switchings use 12mA.
