Texas Instruments has introduced its smallest 6A, 17V step-down synchronous switcher with integrated FETs.
The TPS54620 is designed to fit a complete 6A power design with inductor and capacitors in less than 195mm square.
The 1.6MHz monolithic DC-DC converter supports input voltages from 4.5 to 17V, allowing it to manage 5V and 12V point-of-load designs, such as a wireless basestation or computer server.
“As telecommunications designs become more dense and complex, they need more integrated, highly efficient power management devices that support a 12-V power rail,” said Steve Anderson, senior v-p of TI’s power management business unit.
Achieving a 95% power conversion efficiency and a 25% lower Rds(on) than previous 6A SWIFT devices, the converter is expected to finding uses in the powering of digital signal processors and other embedded processors, such as FPGAs and Asics.
A related product is the TPS54418 4-A switcher with integrated FETs, which supports input voltages from 2.95V to 6V.
The device switches up to 2MHz, can be synchronised and achieve greater than 95-percent power efficiency in a 3x3mm QFN package.
