UCC28250PWR Product Details

UCC28250PWR Overview


This switching controller fits most application requirements since it is packaged in a 20-TSSOP (0.173, 4.40mm Width) package. 2 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). PWM Signal dc switching's outputs (s) are supported. 4.7V~17V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. There is a switch at 85kHz~1.15MHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Current Limit, Enable, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 20 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 12V. You can find other relevant dc to dc converter ics by searching "UCC28250". There are only 20 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 4.7V. DC regulator outputs 20.3V voltage according to the test statistics. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. DC regulator's maximum frequency is 1MHz. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 12V. The supply voltage must be 12V. 3.4mA more than 3.4mA current should be supplied to the controller.
