UC3842AM Product Details

UC3842AM Overview


It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 1 outputs. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). dc controls with 10V~30V voltage are supplied and operated. Work well in dc switchers with a 0°C~70°C TA. The switching controller can be switched at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Through Hole. To provide efficient switching control, Frequency Control is included in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. Different dc switching's functions can be applied to 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. UC*84 can be searched for other relevant dc to dc converter ics. There are only 8 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. The dc to dc regulator is limited to 30V input voltage. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototypes, DC switcher's Through Hole makes it suitable. Switching controllers operate at 500kHz frequencies. 1A is the largest value switching converter outputs. DC switching uses 11mA when it is dormant.
