Power Supply IC: Contributing to improved sound quality from the power line

The power supplied to audio devices can significantly affect the audio quality, so to achieve a clean power supply it is necessary to deliver superior voltage stability and noise level characteristics.
ROHM’s BD37201NUX is a high fidelity power supply IC that excels in providing these two important parameters.
This makes it ideal for digital devices that operate at low voltages (i.e. DACs, DSPs).

<Feature 1: Voltage Stability>
Fast response over a wide range minimizes the effects of the input voltage on the output voltage, allowing the BD37201NUX to express the full range of audio sources such as dynamic bass and intensity without compromising on sound quality.

Power supply rejection ratio (PSRR) indicates the ability to remove input power supply ripple, expressed in units of dB. The higher this number is, the better the performance.

<Feature 2: Noise Level>
Significantly achieving lower noise over conventional products eliminates the effects of noise on the sound, resulting in clear audio with exceptional transparency.
