UC3843D Overview
This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.209, 5.30mm Width) package. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 7.6V~30V. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. Search for "UC3843" to find other relevant dc to dc converter ics. 14 pins are present on switching converter. Statistically, the DC regulator outputs 13.5V voltage. You should note down the dc dc regulator's usual output current of 1A when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controllers work at 500kHz Hz. For nominal working status, the input voltage can be set as 25V. A current of 17mA is supplied to it. nominal current supply for this the controllers dc is 17mA.
