Description

  • PMP10691, High-Efficiency Small form Factor 112W Sync Buck Reference Design. PMP10691 is a single-phase synchronous buck converter rated for 3.3V output at 35A from an input voltage of 12V. This design uses the LM27403 synchronous buck controller. Two CSD87350Q5D power block MOSFETs provide maximum efficiency when combined with a 250nH ferrite output inductor. The design solution uses all ceramic capacitors to fit into a minimum board area

Research and Events

Energy Harvesting with Texas Instruments

The second law of Thermodynamics states that energy will naturally flow from more organized states to lower level states that are more distributed and disorganized. Traditionally, the energy loss was something that was just accepted, but scientists have increasingly been paying attention to this ‘waste’ energy and have developed ways to harness and recover energy that would otherwise naturally dissipate.
