UCC28251PWR Overview

Capsuled in the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. PMIC is packaged in a solid enclosure of Tape & Reel (TR). 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. A -40°C~125°C TJ dc switcher is not a problem. The switching controller is capable of switching at the 42kHz~945kHz position. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, Frequency Control, Ramp, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. A variety of terminations with 20 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. A search for "UCC28251" will reveal other relevant dc to dc converter ics. In total, switching converter has 20 pins. This dc dc voltage regulator should be powered by a voltage of 4.7V. Based on the test statistics, DC regulator outputs voltage 20.3V. You should note down the dc dc regulator's usual output current of 20mA when you start a project. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. There is a maximum frequency of 945kHz for this dc regulators. When running the voltage regulator dc to dc in a circuit, users should apply 12V to ensure safety and reliability. A supply voltage of 12V is required. There is a 2mA volt supply current.
