UC3844BN Overview


With its 8-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. 1 outputs can be generated with the dc motor controller. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. 10V~36V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TA. The switching controller is capable of switching at the Up to 500kHz position. It is suitable for general dc dc regulator when it is set to Through Hole. In order to control switching efficiently, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Various 8 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. A search for "UC384*B" will reveal other relevant dc to dc converter ics. Pins number 8 of switching converter in total. The type is a particular Switching Regulator or Controllers of switching converter. Based on the test statistics, DC regulator outputs voltage 5.1V. A maximum voltage of 25V is accepted by the dc to dc regulator as an input voltage. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 48 %. Having a Through Hole makes DC switcher ideal for most prototype and application designs. There is 275kHz frequency setting on the switching controller. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 30V. When the dc switching is dormant, it uses 12mA.
