UC2843BD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. 1 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 7.6V~30V voltage are supplied and operated. Suitable for work in a -25°C~85°C TA dc switcher. It can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC2843". 8 pins are on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 5V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. Switching controllers work at 500kHz Hz. It is possible to set the input voltage as 15V for nominal working statuses. There is a possibility of damage to the component if the switching voltage regulators current exceeds 500μA.
