Uses low-noise, low-ripple buck converter
High efficiency operation for noise-sensitive applications
Reduces power loss by up to 76% and saves 36% of board space.


Texas Instruments today introduced a new family of low-noise DC/DC switching regulators with integrated ferrite bead compensation.
The TPS62912 and TPS62913 offer low noise of 20µVRMS and ultra-low output voltage ripple of 10µVRMS over frequencies from 100Hz to 100kHz. This allows engineers to eliminate one or more LDO regulators from their designs, reducing power loss by up to 76% and saving 36% of board space.

Traditional low-noise power supply architectures include DC/DC converters, low-noise LDOs (such as the TPS7A52, TPS7A53, and TPS7A54), and off-chip filters (such as ferrite beads). The newly released TPS62912 and TPS62913 integrate ferrite bead compensation, using the ferrite beads already present in most systems as filters to suppress high-frequency noise. This reduces the output voltage ripple of the power supply by approximately 30 dB and simplifies power supply design.

TI will demonstrate the TPS62913 in its virtual booth at the Electronica conference from November 9 to 12.
