UC2573DG4 Overview


As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.75V~30V. Qualified to work in an dc switcher with -40°C~85°C TA. In this switching controller, the switch can be set to 100kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Current Limit, Ramp for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input of 5V. Searching "UC2573" will return other relevant dc to dc converter ics. The switching converter has a total of 8 pins. According to the test statistics, DC regulator outputs 30V voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 500mA. DC regulator has a maximum frequency of 115kHz. In dormant mode, 9mA is used. Users must limit the voltage accordingly because the dc switcher's maximum input voltage is 35V. The supply voltage must be 4.2V. The dc switcher will not provide an output current greater than 500mA. A datasheet states that the switching converter can output 30V volts at its maximum. A voltage controller's lowest output voltage cannot be less than 1.5V.
