UC3843AD8TRG4 Overview


The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. 1 outputs can be generated with the dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. 7.6V~30V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with 0°C~70°C TA. In this switching controller, the switch can be set to Up to 500kHz. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC3843". 8 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. Statistically, DC regulator outputs 15V volts. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. The switching controller works at a frequency of 450kHz. It is possible to set the input voltage as 25V for nominal working statuses. This voltage controller requires a supply voltage of 11V. There should be 25mA more than 25mA amps of current supplied to the controller.
