Highly integrated synchronous power module features up to 95 percent efficiency for space- and height-constrained applications
Texas Instruments (TI) introduced a 5.5-V step-down power module that delivers true, continuous 6-A output current with up to 95 percent efficiency. The easy-to-use 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 6-A 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.

Prototype samples of the TPSM82480 are available now through the TI store. Offered in a 24-pin quad flat micro (QFM) MicroSIP™ package, the module is priced at US$3.57 in 1,000-unit quantities.
