Power module with 65V transient protection announced by TI

Texas Instruments Incorporated (TI) has launched a new power module with 65-V transient protection that integrates a DC/DC converter, inductor and passives in a small 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 thin 9 x 11 mm package.

For applications that require a negative output voltage, TI provides 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 offers 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 power modules are available in volume now. They are offered in a 41-lead QFN package priced at US$5.25 and US$6.00 respectively, in 1,000-unit quantities.
