UC3843AD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. For outputs of 1, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 7.6V~30V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~150°C TJ. It can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. The 8 terminations can be used for a wide range of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics will be returned if you search "UC3843". In total, switching converter has 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. This dc to dc regulator accepts only 30V input voltage at most. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. A frequency of 500kHz is set for the switching controller. When the dc switching is dormant, it uses 12mA.
