Overview
The PTN78000WAZT is a high-efficiency, step-down Integrated Switching Regulator (ISR) produced by Texas Instruments. It represents the third generation in the evolution of the popular 78ST100 series of products. This module is designed to be smaller and lighter than its predecessors, offering either similar or improved electrical performance characteristics. The PTN78000WAZT is compatible with TI's roadmap for RoHS and lead-free compliance and features a case-less, double-sided package with improved thermal characteristics.
