Description

This reference design supports the supply for an audio amplifier, such as the TAS5414C-Q1 using the various DC/DC power switchers, LDOs, logic, clocks, and op amps. This reference design is also applicable in start/stop systems.

Modifying this reference design can also create a power supply for a radio head unit.

Features
  • Wide input operating voltage from 4.5V to 52V
  • Fixed frequency current mode control
  • Internal slope compensation and an integrated low-side driver
  • Programmable close-loop start stop
  • Capable of external synchronization
  • Low current disable function
