UCC28251RGPT Overview
Capsuled in the 20-VFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. For outputs of 2, this dc motor controller is suitable. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With PWM Signal dc switching's output (s), it is able to handle it. DC control operates at 4.7V~17V volts and has 4.7V~17V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. With this switching controller, you can switch at 42kHz~945kHz. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable, Frequency Control, Ramp, Soft Start is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position QUAD . Various 20 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "UCC28251". Pins number 20 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 3.25V. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. There is 945kHz frequency setting on the switching controller. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 12V. 20V is the nominal working voltage. Switching controller is necessary to provide a voltage of 12V. The supply current of the voltage controller is 2mA. The component might suffer damage if the current exceeds 275μA.
