Introduction
Automotive audio amplifiers require a high power boost converter that is both efficient and compact. High efficiency is essential to keep dissipated heat low and avoid bulky and expensive heat sinks. The LT3782A is a 2-phase synchronous PWM controller, making it possible to produce a low profile, high power boost supply that achieves 98% efficiency.
