UC3843D8TR Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. 1 outputs can be generated with the dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 12V~28V. Worked in an dc switcher with a 0°C~70°C TA rating. With this switching controller, you can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . A variety of 8 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. A search for "UC3843" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 8. The type is a particular Switching Regulator or Controllers of switching converter. Based on the test statistics, DC regulator outputs voltage 13.5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. A frequency of 450kHz is used by the switching controller. It is possible to set the input voltage to 25V for nominal working status. In order to ensure proper operation, the controller should not receive more current than 25mA.
