TI introduces first 40-A, 16-Vin buck converter

Texas Instruments introduced the industry’s first 40-A, 16-V_IN synchronous step-down dc/dc converter with differential remote-voltage sensing. The SWIFT TPS548D22 buck converter features a small PowerStack package and integrated MOSFETs to drive ASICs and DSPs in space-constrained applications. It targets wired and wireless communications; enterprise and cloud computing, and data-storage systems designs

The dc/dc converter employs the company’s D-CAP3 adaptive on-time control mode topology, features 0.5% reference-voltage accuracy over temperature, and includes true differential remote-voltage sensing to meet voltage requirements of deep submicron processors. Integrated power MOSFET feature 2.9 mOhm (high-side) and 1.2 mOhm (low-side) RDS(on), is offered in a 40-pin, 5 x 7 x 1.5-mm PowerStack QFN package, allows heat sinks from a single ground pad on the bottom of the device, provides internal soft start, and has input overvoltage protection.
