UC3843BVD Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tube solid enclosure protects the pmic. 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. Worked in a -40°C~105°C TA dc switcher before. This switching controller can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. Various 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. The dc to dc regulator is limited to 25V input voltage. Current is output to the greatest value of 1A.
