UC2573N Overview


It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. 4.75V~30V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. Switching can be done at 100kHz with this switching controller. The Through Hole makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Ramp which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. 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. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. Other relevant dc to dc converter ics will be returned if you search "UC2573". There are only 8 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. A 30V voltage of DC regulator was detected in the test statistics. The dc dc regulator's usual output current is 500mA, which should be noted down when you start a project. Switching controller operates at 300kHz Hz. Dormant dc switchings use 9mA. In order to limit the voltage of a dc switcher whose maximum input voltage is 35V, it must be limited by the user. Voltage 4.2V must be supplied. A dc switcher can only produce an output current of 500mA. Datasheets state the switching converter can output up to 30V volts. 1.5V voltage output is lower than 1.5V.
