UCC28251RGPR Product Details

UCC28251RGPR Overview


The switching controller fits in the 20-VFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are PWM Signal dc switching's output (s) that it can handle. A 4.7V~17V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 42kHz~945kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Ramp, Soft Start which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at QUAD. 20 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics will be returned if you search "UCC28251". Total pins of switching converter are 20. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4.7V as the minimum input voltage of dc dc voltage regulator. A 3.25V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 25mA. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. To operate the voltage regulator dc to dc safely and reliably, users should apply 12V. Voltage 12V must be supplied. There is a 2mA volt supply current. The nominal current supply of this the controllers dc is 2mA.
