Overview
The PTD08A020WAD is a high-performance, 20-A rated, non-isolated digital PowerTrain module produced by Texas Instruments. This module is designed to be the power conversion section of a digital power system, integrating TI's UCD7230 MOSFET driver IC. It must be used in conjunction with a digital power controller such as the UCD9240 or UCD9110 family. The module receives control signals from the digital controller and provides parametric and status information back, forming a sophisticated, robust, and easily configured power management solution.
