Overview
The TPSM63603RDHR from Texas Instruments is a highly integrated synchronous buck DC/DC power module designed for high-density power supply applications. This module combines power MOSFETs, a shielded inductor, and passives in an Enhanced HotRod™ QFN package, making it ideal for space-constrained designs. It offers a wide input voltage range of 3 V to 36 V and an adjustable output voltage range from 1 V to 16 V, with a maximum output current of 3 A. The module is optimized for low-EMI design and requires as few as four external components, simplifying the design process and reducing the overall PCB footprint.
