TB332: An Integrated Synchronous-Rectifier Power IC with Complementary-Switching (HIP5010, HIP5011)
نویسنده
چکیده
A new partitioning approach integrates the power devices and drive of a high-efficiency synchronous-rectified buck converter for numerous advantages in low-voltage power systems. This approach, coupled with a low-cost voltage-mode controller, improves efficiency by eliminating the dissipative current-sensing resistor and reduces size with a smaller inductor. The resulting converter responds faster to dynamic loads typical of the new microprocessors. Integrated power MOSFETs improve switch timing, reduce EMI and ease thermal design issues.
