UC3573D Overview

It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 4.75V~30V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. Switching can be done at 100kHz with this switching controller. The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Current Limit, Ramp is included in the dcdc regulator. 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. There are many different types of terminations for 8. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. Searching "UC3573" will return other relevant dc to dc converter ics. Switching converter has a total of 8 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 30V voltage based on test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 500mA. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at a frequency of 300kHz. Because the dc switcher's maximum input voltage is 35V users must limit the voltage accordingly. There will be 700mA output current greater than 700mA from the dc switcher.
