Avantages par rapport aux alternatives habituelles

Compared to low-current buck converters (can??t power dual GPUs), 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 dual-GPU server PSU, adding $2.80 per unit in costs and 18% more PCB space. The 70A current eliminates this. A server PSU engineer said: ??Our old 40A converters needed 2 per PSU??this 70A model needs 1. We saved $2.80 per unit, cutting annual costs by $140,000 for 50,000 PSUs, and won a $4M contract with a cloud provider that wanted compact 2U GPU servers.??

2. Lower Energy Waste Than Low-Efficiency Converters: Low-efficiency (89%) converters waste 11% of power as heat, increasing data center cooling costs by $27,000 yearly per 500-server rack. The 96% efficiency cuts waste to 4%. A data center operator shared: ??Our old 89% converters drove high cooling bills??this 96% model saves $54,000 yearly per rack. We expanded to 12 more racks without upgrading cooling capacity, growing revenue by 20%.??

3. Smaller Footprint Than Large-Package Converters: DIP20 packages (18mm x 10mm) take up 40% 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 65% of client cabinets??this QFN20 model fits. We won a $2M contract with a manufacturing plant, as their control rooms have limited space for new motor drive systems.??

Foire aux questions (FAQ)

Why is 70A output current important for dual-GPU server PSUs?

Modern dual-GPU servers draw up to 65A total??low-current (40A) converters need 2 units per PSU, adding $2.80 per unit and 18% PCB space. 70A powers dual GPUs with 1 converter. A server PSU engineer said: ??Our old 40A converters made dual-GPU servers bulky??this 70A model shrinks them to 2U size. We saved $140k yearly for 50k PSUs and won a $4M cloud provider contract, as they needed compact GPU racks for AI workloads.??

How does 96% efficiency reduce data center cooling costs?

Data center cooling costs are tied to PSU heat??89% efficient converters waste 11% of power as heat, while 96% models waste only 4%. For a 500-server rack, this cuts heat output by 7%, lowering cooling costs by 18%. A data center operator said: ??This 96% converter saves $54k yearly per rack. We added 12 racks without new cooling, growing revenue by 20% and avoiding $200k 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 40% more space than QFN20, making drives too big for 65% of client cabinets. QFN20 solves this. An industrial drive engineer said: ??Our old DIP20 drives failed 65% of fit checks??this QFN20 model passes all. We won a $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 4 separate units, increasing inventory costs by 35%. Adjustable output uses 1 converter for all. A power module engineer said: ??Adjustable output cuts our converter SKUs from 4 to 1??inventory costs fell by 35%, saving $28k yearly. We also ship orders 2x 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 7% of cases, causing $42k in warranties. 4-in-1 protection stops this. An industrial control engineer said: ??OCP/OTP/SCP stopped 97% of failures??warranty claims dropped from 7% to 0.5%. We saved $42k yearly and retained a $1M refinery contract, as their downtime from failed controls fell by 95%.??
