UC2844BN Overview


As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. Transistor Driver dc switching's outputs (s) are supported. A 10V~30V voltage is supplied to the dc control and used for operating it. Qualified to work in a -25°C~85°C TA dc switcher. A switching controller such as this can switch at a value of Up to 500kHz . A generalization of dc dc regulator can be made using Through Hole. The dcdc regulator features Frequency Control for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . Different dc switching's functions can be applied to 8 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics will be returned if you search "UC2844". In total, switching converter has 8 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 5.05V volts. The dc to dc regulator can only accept a maximum input voltage of 30V. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. As DC switcher has a Through Hole, it's suitable for most applications and prototype designs. A frequency of 500kHz is set for the switching controller. 12mA volts is the supply current. If the current exceeds 17mA, the component may not operate correctly and may even be damaged.
