TPS54974PWP Overview


optimized performance is achieved by utilizing the Tube package in this voltage regulator. This harley voltage regulator has 28 terminations. This regulator voltage is equipped with a type of analog integrated circuit that is called a SWITCHING REGULATOR voltage regulator. There is a 28-PowerTSSOP (0.173, 4.40mm Width) package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs on DC DC switching regulator. Adjusting voltage regulator's output pins generate Adjustable output. This switching regulator is designed to fit the Surface Mount mounting system. -40°C~85°C TA should be the operating temperature when voltage regulator is operating. DC-DC switching regulators reach 350kHz switching frequencies. A dc to dc voltage regulator's minimum input voltage of 3V is required for this voltage regulator to operate. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.891V. There is a maximum input voltage of 4V for this voltage regulator 12v. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 2.5V. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. DC/DC regulators such as this one belong to the TPS54974 family of products. A voltage of 2V volts can be produced by voltage regulator. There are 28 pins used for switching regulator operation. The maximum output current reaches 9A A to meet the switching regulator operation requirements. 3.6V's maximal output voltage allows adjusting voltage regulator to operate easily. In the SWIFT? family, this part palys an important role in DC DC switching regulator's traget applications. This DC-DC switching regulator operates from a supply voltage of 4V. There is no external influence on harley voltage regulator as it consumes 11mA A of quiescent current.
