TPS65251RHA Product Details
TPS65251RHA Overview
For optimal performance, this voltage regulator uses the Tube package. As you can see, this harley voltage regulator contains 40 terminations. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. In order to save space, this harley voltage regulator is available in the 40-VFQFN Exposed Pad package. A total of 3 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. Voltage regulators should be operated at -40°C~125°C TJ temperature while operating. This voltage regulator 12v reaches a switching frequency of 300kHz~2.2MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. A maximum design flexibility is provided by the 3A 2A output current of voltage regulator. The maximum input voltage of voltage regulator is 18V. As a result of its peak reflow temperature, this voltage regulator is virtually indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 12V. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. In this case, the DC/DC regulator belongs to the family TPS65251. A voltage of 800mV volts can be generated by DC DC switching regulator. There are 40 pins that are used for the operation of the voltage regulator 12v. Switching regulators with ALSO HAS PFM CONTROL TECHNIQUE features are highly efficient and stable.
