TPS65257RHAR Overview
A Tape & Reel (TR) package is used in this voltage regulator to optimize performance. A voltage regulator consists of 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. For space-saving purposes, this voltage regulator is available in the 40-VFQFN Exposed Pad package. The voltage regulator 12v has 3 outputs. Adjusting voltage regulator's output pins generate Adjustable output. Surface Mount-mounting is compatible with this switching regulator. The operating temperature should be kept at -40°C~85°C TA when the voltage regulator 12v is in operation. This voltage regulator 12v reaches a switching frequency of 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. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 0.8V. A maximum design flexibility is provided by the 3A 2A output current of voltage regulator. Voltage regulator's input voltage can reach 16V. As a result of the 260 peak reflow temperature, this regulator is essentially indestructible. For operation, voltage regulator provides a nominal input voltage of 12V. The regulator voltage that you are looking at belongs to the subcategory Switching Regulator or Controllers. DC/DC regulators of this type are part of the TPS65257 family of voltage regulator 12vs. Voltage regulator is capable of giving voltage at 800mV volts. For switching regulator operation, 40 pins are used. An external factor does not affect harley voltage regulator's ability to consume 600μA A of quiescent current. Switching regulators with the PFM CONTROL TECHNIQUE ALSO POSSIBLE feature are more efficient and stable than those without.
