The ISL78227 and ISL78229 55V, two-phase synchronous boost controllers with integrated high-side and low-side MOSFET drivers are described as the industry’s most robust and highly integrated boost controllers available to simplify the design of high power automotive applications. Operating from a 12V battery supply, the devices boost the output voltage to 24V, 36V, or 48V for premium 200W to 800W trunk audio amplifiers, start-stop systems, and headlamp LED strings. Both controllers also address the demands of industrial and telecom applications where a step-up dc/dc converter must deliver high power in a compact design.
The ISL78227 55V synchronous boost controller is available now in a 5 mm x 5mm, 32-lead WFQFN package priced at $3.45 each/1,000. An ISL78227EV1Z evaluation board can be purchased for $127 USD each.
