UC2842N Overview
With its 8-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. Tube is the solid enclosure in which PMIC is packaged. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 12V~28V. Worked in a -40°C~85°C TA dc switcher before. It can switch at Up to 500kHz. dc dc regulator can be generalized using Through Hole. DCDC regulator is controlled efficiently by Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. Different dc switching's functions can be applied to 8 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "UC2842". In total, switching converter has 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 13.5V voltage according to the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. 500kHz is the frequency of the switching controller. 25V is the nominal working voltage. It is not recommended to supply more current to the controller than 25mA.
