7.6V~30V 14-Pin UC3843 DC to DC converter IC 1 Outputs Up to 500kHz Transistor Driver
UC3843DX Overview
In the 14-SOIC (0.209, 5.30mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tape & Reel (TR) solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulator500kHz has the maximum frequency. You should keep dc regulator at 0°C degrees or higher. There should be 70°C temperature above 70°C degrees Celsius when dc regulator runs. There would be 14-SOP supplier dc dc controller package for this part. 17mA volts is the supply current. Voltage rating is 30V. There is a nominal current supply of 17mA for this the controllers dc.
