UC2572DG4 Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. For outputs of 1, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 4.75V~30V and has a 4.75V~30V supply voltage. Worked in a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of 100kHz . dc dc regulators can be carried out with Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Ramp. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. An array of 8 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 5V. Other relevant dc to dc converter ics will be returned if you search "UC2572". There are only 8 pins on switching converter. DC regulator outputs -70V voltage based on test statistics. normally, the dc dc regulator's output current is 500mA, which you should keep in mind when starting a project. 300kHz is the maximum frequency of this dc regulators. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 30V. DC switching uses 9mA when it is dormant. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 35V. 4.2V is the required supply voltage. A dc switcher can only produce an output current of 500mA. The datasheet indicates that the switching converter can output -1V volts at its maximum. There is -70V voltage output lower than -70V on the voltage controller.
