Digital amps pose power supply problem

Keywords:digital amplifier  MOSFET H-bridge  SMPS 

Six years ago, digital amplifier technology manufacturers and users faced three major obstacles. First, the signal path changed architectures, second, power was delivered to the speaker through a MOSFET H-bridge, and third, the power supply typically transitioned from a loosely regulated linear supply to a switched-mode power supply (SMPS).

This document by Texas Instruments presents some design guidelines aimed at avoiding common problems in designing with an SMPS and digital amplifier.
