UC3843BVD1G Overview


With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. This dc motor controller can be used to generate outputs with 1 numbers. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. 7.6V~30V is the supply voltage and the operating voltage of the dc control. Worked in a -40°C~105°C TA dc switcher before. The switching controller can be switched at Up to 500kHz. dc dc regulator is made easier with Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. An array of 8 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "UC384*B". There are a total of 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. The test statistics indicate that DC regulator outputs a voltage of 13.4V. The dc to dc regulator can only accept 25V input voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 96 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. Switching controllers operate at 52kHz frequencies. Having a current greater than 17mA may result in improper operation and possibly damage to the component.
