International Rectifier offers a family of 30V synchronous buck MOSFETs for DC-DC synchronous point-of-load (POL) converters. The SO-8 synchronous MOSFETs are designed for high density applications requiring small size, high efficiency and improved thermal conduction, making them ideally suited for notebook applications and point-of-load (POL) converters used in servers, as well as advanced telecom and datacom systems.
The new 30V, N-channel devices are offered in standard D-Pak, SO-8 and the newly introduced “Power QFN” packages that are optimized for the high volume production. The power quad flat-pack no-lead (PQFN) packages provide improved thermal performance and flexibility for new designs within a common SO-8 package form factor.
These new MOSFETs offer significant gate oxide improvement over previous generations and provide high performance as part of a system-wide solution to optimize 12VIN / 1-3VOUT DC-DC synchronous buck converter applications. Low RDS(on) and low Qg makes these new parts ideally suited for point-of-load converter applications. The low conduction losses improve full-load efficiency and thermal performance while the low switching losses help to achieve high efficiency even at light loads. The new devices enable a simplified costeffective migration for existing designs.
