Texas Instruments TPS54020 SWIFT Synchronous Step-Down DC/DC Converter

Texas Instruments TPS54020 SWIFT Synchronous Step-Down Converter

Texas Instruments recently announced their SWIFT 10-A TPS54020 synchronous step-down DC/DC converter. The TPS54020 features integrated MOSFETs, frequency synchronization, 180-degree out-of-phase switching and selectable current limit to power FPGAs, system-on-chip (SoC), DSPs and processors. The TI TPS54020 DC/DC converter is available in volume now in a 15-lead HotRod QFN package. It is priced at $3.45 in 1,000-unit quantities.

The SWIFT 10-A TPS54020 features the highest power density. It is ideal for high-voltage, space-constrained communication, gaming and industrial computing applications.

The new HotRod integrated circuit package protects the integrated MOSFETs from parasitic inductance and allows low resistance. It enables high current and efficiency and small size. The thermally enhanced, 15-lead package is 50% smaller than similar offerings.
