Overview
The LMZ35003RKGT is a 2.5-A power module from Texas Instruments, designed to provide a compact and efficient power solution. This module integrates a DC/DC converter, a shielded inductor, and necessary passives into a low-profile QFN package. The small footprint of 9 mm × 11 mm × 2.8 mm makes it ideal for point-of-load designs, offering greater than 90% efficiency and excellent power dissipation capabilities. The LMZ35003RKGT simplifies the design process by eliminating the need for loop compensation and magnetics part selection, requiring as few as five external components.
