UC2844BNG Overview
With its 8-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 10V~36V voltage are supplied and operated. Qualified to work in a -25°C~85°C TA dc switcher. The switching controller can be switched at Up to 500kHz. A generalization of dc dc regulator can be made using Through Hole. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Search for "UC284*B" to find other relevant dc to dc converter ics. There are only 8 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 13.4V voltage. This dc to dc regulator accepts only 25V input voltage at most. It's important to remember that the dc dc regulator's normaloutput current is 12mA, so you should note it down when starting a new project. The maximum duty cycle of this voltage regulator dc to dc is set to 48 % to ensure reliability during power-up and power-down. The Through Hole makes DC switcher suitable for most applications and prototypes. Switching controller operates at 250kHz Hz. Having a current greater than 17mA may result in improper operation and possibly damage to the component.
