UC2843D8 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. 12V~28V is the operating voltage and supply voltage of the dc control. Worked in a -40°C~85°C TA dc switcher before. With this switching controller, you can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . 8 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "UC2843". There are a total of 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controllers work at 450kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. The controller should not be supplied with more current than 25mA.
