UC2845BN Overview


It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 7.6V~30V. Work well in dc switchers with a -40°C~150°C TJ. With this switching controller, you can switch at 250kHz. As it has a Through Hole value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Search for "UC2845" to find other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. As determined by the test statistics, the output voltage of DC regulator is 5.05V. Considering the dc to dc regulator can only accept 30V input voltage, it is important to take note of this. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. In most applications and prototypes, DC switcher's Through Hole makes it suitable. Switching controller operates at 500kHz Hz. During dormancy, the dc switching uses 12mA. With this controller, the phase is 1. There is a possibility that a current higher than 17mA will cause improper operation of the component and possibly damage switching voltage regulators.
