TPS54974PWPRG4 Product Details
TPS54974PWPRG4 Overview
A Tape & Reel (TR) package is used in this voltage regulator to optimize performance. In this voltage regulator, 28 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 28-PowerTSSOP (0.173, 4.40mm Width) package. 1 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~85°C TA is essential when operating. A DC-DC switching regulator such as this one switches at 350kHz. Voltage regulators like this one can operate at least with 3V 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 0.891V. This voltage regulator 12v features maximum design flexibility thanks to its 9A output current. As far as the voltage input is concerned, DC DC switching regulator can accept up to 4V. Due to its NOT SPECIFIED high peak reflow temperature, this voltage regulator 12v is virtually indestructible. An input voltage of 2.5V 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 TPS54974 family of DC/DC regulators, this is a DC/DC regulator. The voltage DC DC switching regulator can provide is up to 2V volts. During switching regulator operation, 28 pins are used. The maximal output voltage of 3.6V allows adjusting voltage regulator for simple operation. Known as a switching DC-DC regulator, this electronic voltage regulator 12v is part of the SWIFT™ family. There are no external factors that affect DC DC switching regulator's consumption of 11mA A of quiescent current.
