TPS543B20RVFT Product Details

TPS543B20RVFT Overview


optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. Throughout this voltage regulator, there are 40 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. The space-saving 40-LFQFN Exposed Pad package is available for this voltage regulator. The voltage regulator 12v has 1 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. This voltage regulator 12v reaches a switching frequency of 300kHz~2MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 4V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V. A maximum design flexibility is provided by the 25A output current of voltage regulator. There is a maximum input voltage of 19V for this voltage regulator 12v. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. In the particular voltage regulators, the TPS543B20 family is represented. A voltage of 5.5V volts can be generated by DC DC switching regulator. There are 40 pins used for switching regulator operation. In the SWIFT™ family, this part palys an important role in DC DC switching regulator's traget applications.
