1 Introduction

TAS2120 features an integrated boost which is normally used for individual operation. However, this boost can be used to power an accompanying TAS2320 while still taking advantage of the efficiency improving Class-H controller; the total 8W of power delivery from TAS2120 integrated boost is divided for both TAS2120 and TAS2320 operation. The boost sharing mechanism allows woofer-tweeter applications to drive the tweeter with higher peak voltage while using most of the continuous power on the woofer, whereas stereo applications benefit from boost power being dynamically used between left and right channel due to the asymmetric nature of music content.
