TPS54620 - 6A Step-Down Switchers

TIs Smallest 6A, 17V DC-DC Converter is 60% Smaller Package than Multi-Chip Converters

TPS54620 - TI's Smallest 6A, 17V DC/DCTexas Instruments' TPS54620 is one of the industry's smallest single-chip, 6 A step-down switchers with integrated FETs. The 95% efficient device is 60% smaller than today's multi-chip converters, and results in a complete 6 A power solution less than 195 mm2 – one-fourth the size of a postage stamp. The 1.6 MHz monolithic DC/DC converter supports input voltages from 4.5 V to 17 V, allowing it to manage space-constrained 5 V and 12 V point-of-load designs.

In addition to size improvements, the TPS54620 offers a high degree of performance and reliability, such as a highly accurate voltage reference with +/- one percent accuracy over a temperature range. Achieving a 95% power conversion efficiency and a 25% lower Rds(on) than previous 6 A SWIFT devices, the converter easily powers deep sub-micron TI digital signal processors (DSPs) and other embedded processors, such as FPGAs and ASICs.
