Texas Instruments introduced a new power module with 65-V transient protection that integrates a DC/DC converter, inductor and passives in a very 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. Watch a video at www.ti.com/tps84250-prv.
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.
Key features and benefits of the TPS84250 and TPS84259 power modules
- 65-V transient protection eliminates additional system protection components.
- Frequency synchronization reduces noise.
- Compliant to EN55022 Class B electromagnetic emissions standard for low EMI noise.
- Very small, low-profile 9-mm by 11-mm by 2.8-mm QFN package is 75-percent smaller in area than open-frame power modules.
Availability, packaging 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 US$5.25 and US$6.00, respectively, in 1,000-unit quantities.
