Small 2.5-A power module offers 65-V transient protection

September 27, 2012 // By Paul Buckley
Texas Instruments Incorporated has introduced a new power module with 65-V transient protection that integrates a DC/DC converter, inductor and passives in a small, easy-to-use package.

The 2.5-A TPS84250 meets the EN55022 Class B electromagnetic emissions standard and features frequency synchronization to cleanly power noise-sensitive analog circuits in test and measurement, industrial motor control, medical and imaging applications.

The TPS84250 step-down power module supports input voltages from 7 V to 50 V and provides a positive output voltage from 2.5 V to 15 V in a small, thin 9-mm by 11-mm package.

For applications that require a negative output voltage, TI offers the TPS84259 4.5-V to 40-V input, up to 15-W power module with frequency synchronization and low electromagnetic interference (EMI). This new power module provides output voltage down to -17 V for powering sensors, bipolar amplifiers, split-rail data converters and other analog circuits. For clean, low-noise voltage rails, the TPS84250 and TPS84259 modules can be paired with wide-input voltage linear regulators such as the 1-A, 36-V TPS7A4700 and 1-A, -36-V TPS7A3301.

The TPS84250 and TPS84259 join TI’s TPS84k power module family, which also provide power for DSPs and FPGAs that require lower input voltages.

TI offers a variety of tools and support to speed design, including circuit topology calculators for the TPS84250 and TPS84259.

Availability and Pricing

The TPS84250 and TPS84259 power modules are available in volume now from TI and its authorized distributors. They are offered in a 41-lead QFN package and are priced at $5.25 and $6.00, respectively, in 1,000-unit quantities.
