UCC28251PW Overview


In the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 2 output generation. PMIC packaging is solid with a Tube 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. Worked in a -40°C~125°C TJ dc switcher before. A switching controller such as this can switch at a value of 42kHz~945kHz . The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Ramp, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Searching "UCC28251" will return other relevant dc to dc converter ics. There are 20 pins on switching converter. Input voltage of dc dc voltage regulator should be 4.7V. Statistically, DC regulator outputs 20.3V volts. You should note that the dc dc regulator's usual output current is 20mA. 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. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 12V. Voltage 12V is required for supply. The supply current is 2mA. The nominal current supply of this the controllers dc is 2mA.
