Overview
The PTH03050WAZT is a 6 A, 3.3-V input non-isolated power module produced by Texas Instruments. This module is part of the PTH family and features Auto-Track™ sequencing, 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 and is ideal for applications where space, performance, and power-up sequencing are critical.
