E-UC3845BN Overview


It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC packaging is solid with a Tube enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. A switching controller such as this can switch at a value of Up to 500kHz . Through Hole makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a DUAL terminal on the switching converters. 8 terminations with a variety of function. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics will be returned if you search "UC3845". There are 8 pins on switching converter. DC regulator outputs 5V voltage based on test statistics. You should note down the dc dc regulator's usual output current of 200mA when you start a project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Having a Through Hole makes DC switcher ideal for most prototype and application designs. A frequency of 250kHz is used by the switching controller. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. For nominal working status, the input voltage can be set as 15V.
