Application Solutions

TDK-Lambda offers comprehensive power solutions that combine multiple product types to meet specific application requirements. These solutions include AC-DC front-end power supplies, DC-DC converters for intermediate bus architectures, point-of-load regulators, and programmable power for testing. Each solution is designed with proper sequencing, filtering, and protection to ensure reliable operation. Our FAE team can help customize these solutions for your specific voltage, power, and form factor requirements.

Contact our FAE team to discuss your system power requirements and receive a customized solution recommendation.

Distributed power architectures using TDK-Lambda products typically follow a three-stage approach: First, an AC-DC power supply converts mains voltage to an intermediate DC bus (typically 24V or 48V)

Second, isolated DC-DC converters provide isolation and voltage step-down to board-level rails

Third, non-isolated point-of-load converters deliver precise voltages to individual loads. This architecture improves efficiency, reduces wiring losses, and enables hot-swappable redundant configurations. TDK-Lambda offers compatible products at each stage with matching voltage ranges and form factors.

Selecting the right intermediate bus voltage for distributed power systems involves several considerations: 24V DC - common for industrial automation, provides safety advantages with lower voltage

48V DC - standard for telecommunications, allows longer cable runs with less voltage drop

12V DC - used for low-power systems or when safety is paramount. Considerations include: Power level - higher voltages are more efficient for high power

Cable length - higher voltages reduce voltage drop over long distances

Safety requirements - lower voltages may be required for certain applications

Compatibility with existing equipment. TDK-Lambda offers power supplies and converters for all standard bus voltages.

Contact our FAE team to analyze your specific requirements and recommend the optimal bus voltage for your distributed system.

The overall efficiency of a TDK-Lambda power system depends on the architecture and components used: Single-stage AC-DC - up to 96% for high-efficiency models

Two-stage (AC-DC + DC-DC) - typically 88-92% combined efficiency

Three-stage with POL - typically 85-90% end-to-end efficiency. Efficiency considerations: Each conversion stage adds some loss

Higher efficiency components cost more but reduce operating costs

Thermal management requirements decrease with higher efficiency

Total cost of ownership improves with high-efficiency designs. TDK-Lambda's high-efficiency products help minimize energy costs and thermal challenges in distributed power systems.

For energy-sensitive applications, select high-efficiency components at each stage to maximize overall system efficiency.
