True Wireless Stereo (TWS) earbuds

One of the smallest applications in terms of mobile devices has to be true wireless earbuds. Designed to pack as much into the smallest form factor, the challenge has been to make them consume less power, offer better audio, and even include noise-cancellation and biometric monitoring features. All of this while delivering long-battery life. Our ultra-small and wafer level chip-scale packages help you fit in the functionality consumers want.

Design considerations

  • Need to balance extremely long battery lifetimes with always on functionality - energy efficiency extremely important
  • Low power dissipation is crucial in such small wearable devices
  • Need for very small packages or wafer-level chip scale footprints
  • For more power efficient wired charging, the inline Schottky diode can be replaced by two back-to-back MOSFETs
