TITPSM861253RDXR
Overview
The TPSM861253RDXR is a highly integrated, non-isolated point-of-load (PoL) DC-DC power module that delivers a fixed 3.3V output at up to 1A. It integrates the power MOSFETs, shielded inductor, and basic passive components into a compact 4.0mm x 3.3mm QFN package. This module simplifies board design by reducing external component count while operating from a wide input range of 3.8V to 17V.
Why Choose This Part
The module utilizes TI's D-CAP3 control mode to provide fast transient response without the need for complex external compensation networks. Its integrated inductor design significantly reduces EMI and saves up to 50% of PCB area compared to discrete switching regulator layouts. Safety features include cycle-by-cycle overcurrent protection and hiccup mode for ultraviolet protection to ensure robust operation under fault conditions.
Applications
Key Specifications
Getting Started
To evaluate this module, refer to the TPSM86125xEVM evaluation board which provides a reference layout for thermal management and EMI performance. Ensure the input bypass capacitors are placed as close as possible to the VIN and PGND pins of the 7-PowerFQFN package. For high-temperature designs, calculate the derating curves based on the module's 125C maximum operating temperature and the provided thermal resistance data.
