UC3843N Overview


Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 500kHz. Through Hole makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. UC3843 can be used to locate other relevant dc to dc converter ics. Pins number 8 of switching converter in total. The test statistics indicate that DC regulator outputs a voltage of 13V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. The Through Hole makes DC switcher suitable for most applications and prototypes. DC regulator has a maximum frequency of 500kHz. Switching controllers work at 500kHz Hz. At 0°C and above, dc regulator should be kept. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. There would be 8-DIP supplier dc dc controller package for this part. A supply current of 17mA is used to power it. As far as maximum supply voltage is concerned, switching voltage regulators is rated as 30V. There is a nominal current supply of 17mA for this the controllers dc.
