Small: High-Efficiency Split-Rail Supply Reference Design for Portable Audio Applications
Texas Instruments
Differential Headphone amplifiers require positive and negative voltages. In this reference design: both voltages are generated from a single input voltage with an all integrated split-rail converter. It only requires one inductor and a minimal amount of external components to achieve a high efficiency power supply that keeps the distortion of the system very low. End users benefit from High Fidelity audio performances with longer playback time in their mobile application.
Features
- 90% Peak EfficiencyTiny solution size: 5.9x6.9 mmLow Distortion: THD+N Programmable outputsSmall BOM — only 7 external components requiredThis circuit design is tested. All necessary software: a Test Report and a Design File are included.
