TDK-Lambda

What TDK-Lambda does

TDK-Lambda is a global supplier of power conversion products, wholly-owned by TDK Corporation since its October 2008 integration into TDK's Power Systems Business Group. The company offers a catalog of over 6,000 standard models spanning AC-DC power supplies (15W to 45,000W), DC-DC converters, programmable DC and AC power sources (including the GENESYS+ series from 1kW to 22.5kW and rack systems up to 90kW), high voltage capacitor charging supplies, electronic loads, and RF generators and matching networks for semiconductor and plasma applications. Underlying technologies include GaN semiconductors, bridgeless totem pole PFC topologies, full digital control via PMBus/LAN/USB/EtherCAT/Modbus-TCP, and multiple thermal management options including liquid cooling. The portfolio is supported by over 700 patents and 70+ years of field-proven design heritage.

The company serves industrial automation, healthcare/medical (where it became the #1 global power supply manufacturer in 2017 per IHS Market), semiconductor fabrication, ICT infrastructure, test and measurement, and avionics/defense OEMs, with products certified to IEC 60601-1 with 2xMOPP isolation, ISO 13485, MIL-STD, and ITAR (at the New Jersey facility). Six global engineering centers in Japan, China, Singapore, UK, Israel, and the USA, combined with owned manufacturing in five regions, enable both catalog sales and the Power+ value-add customization program that delivers bespoke thermal, EMI, cabling, and firmware solutions built on standard product building blocks.

TDK-Lambda generates revenue primarily through one-time hardware sales via a multi-channel model: direct enterprise field sales targeting large OEM accounts, a network of 600+ authorized distributors carrying $25+ million in inventory across five regions, sales representatives, and a direct-to-consumer e-commerce site (genesysdcstore.com) for programmable DC power supplies. Pricing is largely quote-based, reflecting the custom engineering and certification complexity of the product line. Recent strategic moves include the 2025 QEI RF power business acquisition, the 2026 Apple American Manufacturing Program partnership committing to US manufacturing expansion by 2030, and a sustained cadence of new product launches across DIN-rail, buck-boost DC-DC, and conduction-cooled AC-DC modules.
