DC/DC step-down power module delivers 6A performance
A 5.5V step-down power module that delivers a continuous 6A output current with up to 95% efficiency has been introduced by Texas Instruments. The TPSM82480 DC/DC module integrates power Metal-Oxide Semiconductor Field-Effect Transistors (MOSFETs) and shielded inductors into a tiny, low profile footprint for space- and height-constrained applications such as point-of-load telecommunications, networking, and test and measurement power supplies.
TI’s highly integrated TPSM82480 maintains the required 6A output current over the full temperature range without additional airflow.
This is accomplished using a two-phase control topology that shares the load between the phases to ensure high efficiency and balanced operation.
Additional features include adjustable soft start, voltage select (VSEL) to support multiple processor stages, and a power-good indicator.
TPSM82480 key features and benefits
- Ultra-small size: Two input/output capacitors and two resistors make up a complete solution footprint of 80mm2 that measures just 1.5mm in height.
- High efficiency: An optional automatic power-save mode maintains high efficiency across the full load range.
- Heat protection: Thermal-good output to alert the system to reduce power before overheating.
