The TPS56428DDAR from Texas Instruments is a 4A synchronous buck converter with 4.5-17V input and adjustable output down to 0.6V in an SOIC-8 package. With 600kHz switching, 92% efficiency, and internal compensation, it provides a simple 4A point-of-load supply with minimal external components.<\/p>\n
