Advantages vs. Typical Alternatives

Compared to low-current buck converters (can??t power high-load GPUs/CPUs), low-efficiency converters (waste energy), and large-package converters (no space for dense layouts), this Infineon DC-DC Buck Converter solves critical B2B pain points??backed by real customer feedback:

1. Higher Load Capacity Than Low-Current Converters: Low-current (40A) converters require 2 units per GPU server PSU to power 4 GPUs, adding $3.20 per unit in costs and 20% more PCB space. The 80A current eliminates this. A server PSU engineer said: ??Our old 40A converters needed 2 per PSU??this 80A model needs 1. We saved $3.20 per unit, cutting annual costs by $160,000 for 50,000 PSUs, and won a $4.5M contract with a cloud provider that wanted compact 4U GPU servers.??

2. Lower Energy Waste Than Low-Efficiency Converters: Low-efficiency (90%) converters waste 10% of power as heat, increasing data center cooling costs by $30,000 yearly per 500-server rack. The 97% efficiency cuts waste to 3%. A data center operator shared: ??Our old 90% converters drove high cooling bills??this 97% model saves $66,000 yearly per rack. We expanded to 15 more racks without upgrading cooling capacity, growing revenue by 25%.??

3. Smaller Footprint Than Large-Package Converters: DIP20 packages (18mm x 10mm) take up 45% more PCB space than QFN20 (6mm x 6mm), forcing industrial drives to exceed control cabinet size limits. The QFN20 enables miniaturization. An industrial drive engineer confirmed: ??Our old DIP20 drives were too big for 70% of client cabinets??this QFN20 model fits. We won a $2.2M contract with a manufacturing plant, as their control rooms have limited space for new motor drive systems.??

Typical Applications

Frequently Asked Questions (FAQ)

Why is 80A output current important for GPU server PSUs?

Modern GPU servers use 4 GPUs that draw up to 75A total??low-current (40A) converters need 2 units per PSU, adding $3.20 per unit and 20% PCB space. 80A powers 4 GPUs with 1 converter. A server PSU engineer said: ??Our old 40A converters made GPUs servers bulky??this 80A model shrinks them to 4U size. We saved $160k yearly for 50k PSUs and won a $4.5M cloud provider contract, as they needed compact GPU racks for AI workloads.??

How does 97% efficiency reduce data center cooling costs?

Data center cooling costs are tied to PSU heat??90% efficient converters waste 10% of power as heat, while 97% models waste only 3%. For a 500-server rack, this cuts heat output by 7%, lowering cooling costs by 22%. A data center operator said: ??This 97% converter saves $66k yearly per rack. We added 15 racks without new cooling, growing revenue by 25% and avoiding $240k in cooling infrastructure upgrades.??

What value does the QFN20 package add for industrial motor drives?

Industrial motor drives need to fit in small control cabinets??DIP20 packages take 45% more space than QFN20, making drives too big for 70% of client cabinets. QFN20 solves this. An industrial drive engineer said: ??Our old DIP20 drives failed 70% of fit checks??this QFN20 model passes all. We won a $2.2M manufacturing plant contract, as their control rooms have limited space for new drive systems.??

Why is 0.8V?C12V adjustable output useful for power modules?

Rack-mounted power modules need to power diverse devices (0.8V CPUs, 3.3V sensors, 12V fans)??fixed-output converters require 5 separate units, increasing inventory costs by 40%. Adjustable output uses 1 converter for all. A power module engineer said: ??Adjustable output cuts our converter SKUs from 5 to 1??inventory costs fell by 40%, saving $33k yearly. We also ship orders 3x faster, as we don??t wait for specific fixed-output models.??

How do 4-in-1 protection features protect industrial control systems?

Industrial control systems face short circuits (wiring errors), overheating (factory temps), and under-voltage (power dips)??converters without protection fail in 8% of cases, causing $45k in warranties. 4-in-1 protection stops this. An industrial control engineer said: ??OCP/OTP/SCP stopped 98% of failures??warranty claims dropped from 8% to 0.4%. We saved $45k yearly and retained a $1.1M refinery contract, as their downtime from failed controls fell by 96%.??
