TPS65251RHAR Product Details

TPS65251RHAR Overview


A Tape & Reel (TR) package is used in this voltage regulator to optimize performance. In this voltage regulator, 40 terminations are present. 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 voltage regulator is packaged in the 40-VFQFN Exposed Pad package. 3 outputs of voltage regulator are configured. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. Keeping dc to dc voltage regulator's operating temperature at -40°C~125°C TJ is essential when operating. A DC-DC switching regulator such as this one switches at 300kHz~2.2MHz. Voltage regulators like this one can operate at least with 4.5V as the dc to dc voltage regulator's minimum input voltage. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. This voltage regulator 12v features maximum design flexibility thanks to its 3A 2A output current. Due to its 260 high peak reflow temperature, this voltage regulator 12v is virtually indestructible. An input voltage of 12V is required to meet the requirements of the switching regulator operation. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. As a member of the TPS65251 family of DC/DC regulators, this is a DC/DC regulator. During switching regulator operation, 40 pins are used. Ideally this switch regulator should have an output voltage of about 800mV at the very least. DC DC switching regulator offers a maximum output voltage of 18V as its maximum output voltage. DC-DC switching regulator with supply voltage 18V. There are no external factors that affect DC DC switching regulator's consumption of 20mA A of quiescent current. Switching regulators with the ALSO HAS PFM CONTROL TECHNIQUE feature are more efficient and stable than those without.
