The 2024 PowerBest power-conversion and management winners, reported by Electronic Design on January 24, 2025, cover five different engineering problems: isolated bias supplies, compact GaN power stages, hybrid supply control, high-voltage offline conversion, and notebook voltage regulation. The list is best read as a set of application-specific component solutions—not as a single ranking of interchangeable products.
What the 2024 PowerBest list covers
Electronic Design framed the awards around integration and conversion architectures intended to make power systems simpler, denser, and more efficient. The winners span automotive, industrial, energy, and computing designs; the right comparison is therefore based on the power-stage role and design constraints, not on a universal “best” part.
| Winner | Power-conversion role | Intended design context |
|---|---|---|
| Texas Instruments UCC33420-Q1 and UCC33420 | Isolated DC-DC bias modules | Automotive and industrial bias supplies |
| Texas Instruments LMG2100R044 and LMG3100R017 | 100-V integrated GaN power stages | Mid-voltage, high-density power conversion |
| ROHM Semiconductor LogiCoA | Hybrid power-supply control architecture | Supply designs across a broad power range |
| Power Integrations 1700-V InnoMux-2 | Single-stage offline GaN power-supply ICs | High-voltage industrial and energy systems |
| Alpha and Omega Semiconductor AOZ71137QI | Three-rail, seven-phase controller | Intel-based notebook voltage regulation |
Texas Instruments: isolated bias and integrated GaN
UCC33420-Q1 and UCC33420 isolated modules
These 1.5-W isolated DC-DC modules integrate the transformer, removing the need for a separate external transformer in the solution. According to the figures reported by Electronic Design in January 2025, TI claims more than 89% solution-size reduction, up to 75% lower height, and a 50% bill-of-materials reduction versus discrete solutions. Those are comparative solution claims, not a guarantee for every board: the practical result depends on the reference design, isolation and layout requirements, and which discrete components a design replaces.
The integrated approach is relevant when an automotive or industrial design needs isolated bias power but has tight space or component-count constraints. The “Q1” designation appears on one of the named parts; verify the exact device variant and qualifications against the manufacturer’s current documentation before selecting it for a specific end product.

LMG2100R044 and LMG3100R017 100-V GaN stages
These integrated 100-V gallium-nitride stages use thermally enhanced packages designed for cooling from both sides. Electronic Design reports TI figures of 1.5 kW/in³ power density, solution-size reductions of 40% or more, and switching losses up to 50% lower than comparable silicon. These figures are presented as TI claims in the awards coverage; they should not be treated as a direct prediction of system performance without matching operating conditions, thermal design, switching frequency, and comparator.
For a design team, the key appeal is integrating the GaN power stage while addressing heat extraction in the package. Check cooling implementation and board layout alongside the headline density and loss figures: thermal performance and achievable density depend on the assembled system, not only the device package.

ROHM Semiconductor: LogiCoA hybrid control
LogiCoA is an architecture for power supplies designed across a stated 30-W to 1-kW range, as reported by Electronic Design in January 2025. It combines a specialized low-power microcontroller with analog circuitry rather than treating the control strategy as wholly digital or wholly analog.
The reported control capabilities include a three-channel comparator, timer linkage, DAC control, and nonvolatile recording of control parameters and operating logs. These features are pertinent where a designer wants configurable control while retaining analog functions and a record of operating information. The 30-W-to-1-kW range describes the supported design range in the coverage; it does not mean one LogiCoA implementation covers that entire span without topology and component changes.

Its reported functions include transient control, phase-current sensing, undervoltage, overvoltage, overcurrent, and overtemperature protection, plus programmable SMBus behavior and telemetry. This makes the device a platform-oriented voltage-regulation option rather than a general-purpose supply controller. Compatibility with the target processor platform and paired power stages is central to selection.

How to compare the winners for a real design
Start with the job the component must perform, then compare only the characteristics that affect that job. The award coverage provides different kinds of evidence for each product, so a numerical comparison across all five would be misleading.
- For isolated bias power: evaluate isolation requirements, power level, board height, footprint, and the discrete transformer-based solution the module would replace.
- For a GaN power stage: compare voltage class, switching-loss conditions, density target, package cooling, and the thermal path available in the finished assembly.
- For power-supply control: consider the control architecture, power range of the intended design, required analog and digital functions, and whether stored parameters or operation logs matter.
- For high-voltage multi-output conversion: verify input and output operating conditions, output independence, isolation and regulation behavior, and system-level safety requirements.
- For notebook voltage regulation: confirm the supported Intel IMVP generation, processor platform, compatible DrMOS or Smart Power Stage devices, and required telemetry and protections.
The winners are component-level engineering products. The awards article does not establish current price, stock, or supply-channel availability, and a recognition does not replace checking current manufacturer specifications and design documentation. Confirm those details with the manufacturers or authorized distributors for the exact part and application.
