Product Summary

The TPS54521RHLT is a full featured 17V, 5A synchronous step down converter which is optimized for small designs through high efficiency and integrated 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 inductor footprint. Applications are (1)Flat Panel Digital TVs; (2)Set Top Boxes, Personal Video Recorders; (3)Net Books; (4)High Density 3.3V/5V Power Distribution from 12 V Bus.
