E-UC3843BN Overview


The switching controller fits in the 8-DIP (0.300, 7.62mm) package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tube. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 500kHz. dc dc regulators can be carried out with Through Hole. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3843". 8 pins are on switching converter. As determined by the test statistics, the output voltage of DC regulator is 13.5V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. In most applications and prototypes, DC switcher's Through Hole makes it suitable. A frequency of 250kHz is used by the switching controller. Input voltage can be set to 15V for nominal working status.
