As the performance of electronic devices such as servers, automotive ECUs, graphics cards, and communications equipment continues to improve, POWER SUPPLIES circuits are required to be more efficient and smaller than ever before. DC/DC converters in particular must be able to handle high currents within a limited board area while simultaneously suppressing SWITCHES losses caused by the on/off operation of MOS FETS and conduction losses due to on-resistance.
Vishay's PowerPAIR® series is a "Half-Bridge MOS FETS stage" that integrates the high-side and low-side MOS FETS used in DC/DC converters into a single package. By optimizing the internal SWITCHES node connection, the parasitic INDUCTORS that is unavoidable in DISCRETE configurations is significantly reduced, simultaneously achieving high efficiency, compact size, and high reliability.
This article systematically summarizes the technical features of PowerPAIR®, comparisons with competing products, application examples, and the product lineup, providing a perspective for considering optimal options for next-generation DC/DC converter designs.
Technical explanation
What is PowerPAIR®?
PowerPAIR® is an integrated MOS FETS power stage that combines a high-side (control) MOS FETS and a low-side (synchronous rectification) MOS FETS in a single package. By internally connecting the half-bridge configuration with the shortest possible distance, parasitic INDUCTORS is significantly reduced, suppressing voltage ringing and EMI during SWITCHES.
Furthermore, Vishay's Gen IV MOS FETS technology achieves both low RDS(ON) and low Qg, significantly contributing to high-frequency operation and improved power density.
PowerPAIR® Technical Advantages
High efficiency
Optimized internal connections reduce SWITCHES and conduction losses, resulting in efficiency improvements of up to 1.5% compared to comparable DISCRETE solutions.
Reduced board area
The PowerPAIR® 6x5FSW is extremely compact at just 31mm², achieving approximately 50% space savings compared to a configuration with two DISCRETE MOS FETS (approximately 62mm²).
Automotive quality (Wettable Flank)
The step-cut TERMINALS stabilize the solder fillet formation, making AOI (Automated Optical Inspection) easier. With a high reliability of 175°C, it is also ideal for automotive ECU and ADAS applications.
Improved thermal performance (Flip-Chip structure)
By flip-chip fabricating the low-side MOS FETS,
- Reduced thermal resistance inside the package
- Expanded contact area with PGND
- Suppresses temperature rise during high current
There are thermal benefits.
