E-UC3845BD1 Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. There is sufficient capacity to generate switching controller for outputs 1. Tube solid enclosure protects the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. The supply and operating voltage of the dc control are 7.6V~30V. A 0°C~70°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 8 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC3845". Pins number 8 of switching converter in total. DC regulator outputs 5.1V voltage based on test statistics. You should note that the dc dc regulator's usual output current is 1A. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. A frequency of 250kHz is set for the switching controller. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability.
