UC2573D Overview


In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 4.75V~30V volts and has 4.75V~30V supply voltage. Suitable for a -40°C~85°C TA dc switcher. There is a switch at 100kHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Current Limit, Ramp for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 8 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. A search for "UC2573" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 8. Statistically, the 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. There is a maximum frequency of 115kHz for this dc regulators. DC switching uses 9mA when it is dormant. The dc switcher's maximum input voltage is 35V; users must limit it accordingly. Voltage 4.2V is needed for the supply. In this case, the dc switcher won't produce more than 500mA watts of output current. At its maximum output, the switching converter can provide 30V volts. 1.5V voltage output is lower than 1.5V.
