Integrated DC/DC step-down power module suits constrained spaces

The DC/DC module integrates power MOSFETs and shielded inductors into a small, low-profile footprint for PoL telecommunications, networking, test and measurement power supplies and other space- and height-constrained applications.


The module maintains the required 6A output current over the full temperature range without additional airflow through the use of a two-phase control topology that shares the load between the phases for efficiency and balanced operation. Thermal-good output to alert the system to reduce power before overheating.


There is also adjustable soft start, voltage select (VSEL) to support multiple processor stages, and a power-good indicator. An optional automatic power-save mode maintains high efficiency across the full load range.



Two I/O capacitors and two resistors make up a footprint of 80mm2 that measures just 1.5mm in height.


Prototype samples are available now in a 24-pin quad flat micro (QFM) MicroSIP package. There is also the TPSM82480EVM-002 evaluation module and PSpice transient models available for download.
