TPS54973PWPRG4 Product Details

TPS54973PWPRG4 Overview


For optimal performance, this voltage regulator makes use of the Tape & Reel (TR) package. In this voltage regulator, there are a total of 28 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. There are 1 outputs configured on this voltage regulator 12v. There are output pins on this DC DC switching regulator that generate Adjustable output. This DC-DC switching regulator has a switching frequency of 550kHz. It features maximum design flexibility due to dc to dc voltage regulator's 9A output current. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 3.3V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. There are 28 pins that are used for the operation of the voltage regulator 12v. The maximum output current reaches 9A A to meet the switching regulator operation requirements. 4V is the supply voltage for this DC-DC switching regulator. Despite external influences, voltage regulator consumes 11mA A of quiescent current. The high-limit maximum operating temperature 85°C allows harley voltage regulator stable operation. To ensure reliability, harley voltage regulator operates at a minimum operating temperature of -40°C. Input voltages as low as 3V can be used for DC DC switching regulator. It is designed to sustain a dc to dc voltage regulator's maximum 4V input voltage. There are 28 pins on this DC-DC switching regulator. The DC DC switching regulator's voltage output is 2.5V.
