UC3842BD1 Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 10V~30V and has a 10V~30V supply voltage. A 0°C~70°C TJ dc switcher is not a problem. This switching controller can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. A search for "UC3842" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 8. In particular, switching converter belongs to the Switching Regulator or Controllers family. A 5.1V voltage of DC regulator was detected in the test statistics. It should be noted that the dc to dc regulator only accepts 30V voltage as input voltage. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. Switching controllers operate at 500kHz frequencies.
