Description

This reference design implements a 10 amp, two-phase boost converter with an adjustable output voltage that can be dynamically set for voltages from 16V to 40V DC. The output voltage range allows tracking an audio signal when provided by either a PWM signal from a processor or a voltage.

Features
  • PWM or DC level control of output voltage
  • Allows adjustment of audio amplifier power supply to match signal conditions
  • Input Voltage Range: 9V to 16V
  • Output Voltage Range: 16V to 40V
  • 10 amp output
