EL SEGUNDO, Calif.--(BUSINESS WIRE)-- International Rectifier, IR® (NYS: IRF) , a world leader in power management technology, today introduced the IR3823 SupIRBuck® integrated voltage regulator designed for space-constrained, energy efficient netcom, server and storage applications.
The IR3823 delivers up to 3A with superior efficiency in an ultra-compact 3.5x3.5mm package. Efficiencies in excess of 97.5% are obtainable for designs converting power from a 6V input to a 4.8V output. The extremely high initial efficiency allows switching at up to 1.5MHz from a 12V supply to enable a complete 3A power supply solution in less than 130mm2. Featuring constant frequency and virtually jitter-free operation with synchronization capability, the new device is well suited to noise-sensitive applications, while the higher bandwidth reduces component count to shrink PCB footprint. A tri-level selectable soft-start feature is also offered for ease of sequencing.
"Offering excellent thermal performance, the IR3823 is an easy-to-implement solution in less than 130mm2 that allows power conversion directly from a 12V input for space constrained, low current point-of-load applications that require benchmark performance," said Ramesh Balasubramaniam, Director of Marketing, IR's Enterprise Power Business Unit.
The IR3823 features programmable switching frequency from 300kHz to 1.5MHz. Other key functions include thermally compensated over-current protection, output over-voltage protection and thermal shutdown.
