UC3843ADR2 Product Details

UC3843ADR2 Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 8.4V~30V. Suitable for working in an dc switcher that has a 0°C~70°C TA. Switching can be done at Up to 500kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of 14 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "UC384*A" to find other relevant dc to dc converter ics. In total, switching converter has 14 pins. There is a particular type of Switching Regulator or Controllers in switching converter. dc dc voltage regulators should have a minimum input voltage of 8.2V. A 5.1V voltage of DC regulator was detected in the test statistics. There is 60kHz frequency setting on the switching controller. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 30V. A value of 1A is output as the maximum value of current. When the dc switching is dormant, it uses 500μA.
