200W with 98% Efficiency вЂ“ Design Note 455
by Victor Khasiev
Introduction
Automotive audio ampliп¬Ѓers require a high power boost
converter that is both efп¬Ѓcient and compact. High
efп¬Ѓciency 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 proп¬Ѓle, high power boost
supply that achieves 98% efп¬Ѓciency. Output power is 200W continuous and 250W for short
pulse loads, corresponding to 8.5A continuous current
and 10.5A pulsed current.
This circuit comprises three major sections. Two are
the phase-interleaved power trains, and the third is
the control circuit.
Each power train includes an inductor, two switching
MOSFETs, a synchronous MOSFET and an output
capacitive п¬Ѓlter. The output п¬Ѓlters are connected
together in parallel. Schottky diodes D1 and D2 increase
efп¬Ѓciency during the dead time. A 24V Output Boost Converter at 8.5A
(Continuous), 10.5A (Peak) from a Car Battery
Figure 1 shows a boost converter that generates …
