UCC28251RGPR Overview


In the 20-VFQFN Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. It is capable of handling PWM Signal dc switching's outputs (s). 4.7V~17V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. Using this switching controller, it is possible to switch at 42kHz~945kHz. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Ramp, Soft Start which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. 20 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. In addition to "UCC28251", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 20. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator must be 4.7V. Statistically, the DC regulator outputs 3.25V voltage. The dc dc regulator's usual output current is 25mA, which should be noted down when you start a project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. The Surface Mount makes DC switcher suitable for most applications and prototypes. A circuit should contain 12V in order to ensure the voltage regulator dc to dc runs safely and reliably. This voltage controller requires a supply voltage of 12V. It runs on a supply current of 2mA. There is a nominal current supply of 2mA for this the controllers dc.
