UCC28250RGPR Overview
Capsuled in the 20-VFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with PWM Signal dc switching's output (s). dc switching'sdc controls with 4.7V~17V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. Using this switching controller, it is possible to switch at 85kHz~1.15MHz. A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Ramp, Soft Start which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . A variety of terminations with 20 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. UCC28250 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 20 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.7V. DC regulator outputs 20.3V voltage according to the test statistics. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. There is a maximum frequency of 1MHz for this dc regulators. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 12V. A supply voltage of 12V is required. The controller should not be supplied with more current than 3.4mA.
