Overview
The PTH03050WAZ is a non-isolated power module from Texas Instruments, part of the PTH03050 series. It is one of the smallest power modules available, featuring Auto-Track™ technology, which simplifies supply voltage sequencing in power systems by enabling modules to track each other or any external voltage during power up and power down. Despite its small size (0.87 in × 0.5 in), the module is capable of delivering up to 6 A of output current, making it ideal for applications where space, performance, and power-up sequencing are critical.
