TPS54622RHLT

Product Summary

The TPS54622RHLT is a step down converter. The TPS54622RHLT in thermally enhanced 3.5mm x 3.5mm QFN package is a full featured 17V, 6A synchronous step down converter which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductors footprint. Applications are (1)High Density Distributed Power Systems; (2)High Performance Point of Load Regulation; (3)Broadband, Networking and Optical Communications Infrastructure.
