Automotive Tracking Power Supply Reference Design for Audio Amplifiers
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 voltageAllows adjustment of audio amplifier power supply to match signal conditionsInput Voltage Range: 9V to 16VOutput Voltage Range: 16V to 40V10 amp output
Applications
- Automotive external amplifier
- Aftermarket audio amplifier
- Virtual engine sound system (VESS)
