TI: small 5.5-V DC/DC step-down power module delivers true 6-A performance
Texas Instruments 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 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.
Two input/output capacitors and two resistors make up a complete solution footprint of 80 mm² that measures just 1.5 mm in height.
