TPS54320 - Texas Instruments

TPS54320 3-A Synchronous Step-Down Converter

The TPS54320 is a full-featured 17-V, 3-A 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 footprint of the inductor. T.
