UC3843BN Overview
The switching controller fits in the 8-DIP (0.300, 7.62mm) package and is ideal for most applications. 1 outputs are supported by the dc motor controller. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Suitable for work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 500kHz. The Through Hole allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. 8 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. UC384*B can be searched for other relevant dc to dc converter ics. Pins number 8 of switching converter in total. Switching converter is a type of Switching Regulator or Controllers in particular. A 5.1V voltage of DC regulator was detected in the test statistics. The dc to dc regulator is limited to 25V input voltage. If you start a project, note down the dc dc regulator's usual output current of 1A. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 96 % during power-up and power-down. Switching controllers operate at 60kHz frequencies. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability. In a dormant state, the dc switching uses 12mA.
