The TPSM84209RKHT is a Non-Isolated Point-of-Load (PoL) module from Texas Instruments, integrating a power inductor, MOSFETs, and controller in a compact 4.5x4mm 9-PowerQFN package. It supports buck, inverting buck-boost, and synchronous buck topologies with a wide input voltage range of 4.5V to 28V. The output is adjustable from 1.2V to 6V with a maximum output current of 2.5A.
This module employs current mode control with a fixed switching frequency of 750kHz (578kHz to 923kHz range), achieving up to 86.5% efficiency. Features include adjustable current limit, enable input, light-load efficiency (Eco-mode), overcurrent protection, and remote on/off. The device operates over an ambient temperature range of -40°C to 85°C with a junction range of -40°C to 125°C and a thermal resistance of 29.5°C/W.
The surface-mount package (9-QFN-FCMOD 4.5x4) has a low profile of 2.1mm, making it suitable for space-constrained designs. The module is intended for commercial ITE (Information Technology Equipment) applications. Compliance data indicates RoHS3 compliance, MSL 1, and REACH unaffected, though these have not been independently verified.
