UC3843DX Product Details
UC3843DX Overview
With its 14-SOIC (0.209, 5.30mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tape & Reel (TR). 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. A 0°C~70°C TA dc switcher is not a problem. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. UC3843 can be searched for other relevant dc to dc converter ics. Total pins of switching converter are 14. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulator500kHz has the maximum frequency. Keep dc regulator at a temperature of 0°C or above. DC regulator should run at a temperature 70°C higher than 70°C. Its supplier dc dc controller package is 14-SOP. With a current supply of 17mA, it runs. A maximum supply voltage of 30V is specified. For this the controllers dc, the nominal current supply is 17mA.
