EPC2361 GaN FETs Power ADI 4 kW Buck-Boost Reference Design: Buyer Checklist
On October 20, 2026, Efficient Power Conversion (EPC) reported that its EPC2361 100 V GaN FETs are used in Analog Devices’ EVAL-LT7930-AZ dual-phase buck-boost reference design. The platform uses ADI’s LT7930 controller and targets up to 4 kW at 48 V output. This October 21 JZP Components briefing separates the confirmed design data from actual purchasing conditions.
What the Manufacturer Sources Confirm
- GaN switching device: EPC2361, an enhancement-mode 100 V GaN FET. EPC states a typical 0.75 mΩ on-resistance, 133 A device rating and 3 mm × 5 mm package; these are device specifications, not system output ratings.
- Controller: ADI LT7930, a parallelable four-switch buck-boost controller designed for GaN FETs and silicon MOSFETs; ADI lists it as recommended for new designs.
- Evaluation hardware: EVAL-LT7930-AZ uses two LT7930 controllers in a two-phase interleaved arrangement, operating at a nominal 150 kHz switching frequency with 180° phase offset.
- Board-level operating point: 36–65 V input, regulated 48 V output, up to 4 kW output capability in the documented reference design.
- Reported typical efficiency: EPC states 98.5% at 36 V and 48 V input and 98.8% at 65 V input under its reported evaluation conditions. These are not guarantees for every load or operating environment.
- Gate timing: EPC reports a 10 ns dead-time setting on this evaluation platform; engineering teams should confirm the final values against current design files and validation results.
- Commercial statement: EPC states EPC2361 is sold through its distribution network; ADI publishes evaluation-board documents and LT7930 product data. Neither source establishes a specific buyer’s on-hand stock, delivered price or lead time.
Why It Matters to Industrial and Telecom Buyers
High-current 48 V rails appear in telecom infrastructure, battery-backed DC power, industrial equipment and power conversion stages. A published multi-kilowatt reference design can shorten the initial engineering evaluation process, but it is not a substitute for thermal, electromagnetic compatibility, reliability and manufacturability validation. Purchasing teams should distinguish a reference-design BOM from a production-qualified customer BOM.
Procurement Signal: Confirmed vs. Not Confirmed
Confirmed: EPC's October 20 reference-design announcement, EPC2361 device identity, ADI LT7930 controller documentation, the EVAL-LT7930-AZ architecture and stated performance figures.
Not confirmed: buyer-specific distributor quantities, contract prices, lead times, production qualification, broad GaN shortages, new wafer capacity, or price increases.
JZP interpretation: a useful design-in and RFQ opportunity for high-power 48 V systems. A working reference design does not automatically imply mass-production availability of every BOM component.
RFQ and Engineering Verification Checklist
- Request EPC2361 by exact MPN and separately specify the desired LT7930 orderable suffix and quantity; include EVAL-LT7930-AZ only when the evaluation hardware itself is needed.
- Download the latest ADI evaluation-board schematic, BOM, user guide and LT7930 datasheet. Confirm board revision, quantity-per-board, passive ratings and sourcing substitutions before converting the design to production.
- Validate actual input range, 48 V output regulation, load transients, thermal dissipation, heatsinking, PCB stack-up, creepage/clearance and EMI performance for the end application.
- Obtain dated, channel-verified quotations covering quantity breaks, date codes, package/packing format, country of origin, traceability, and firm delivery commitments.
- For second-source planning, compare the full gate-drive, dead-time, switching loss, package and thermal envelope; do not assume a same-voltage silicon MOSFET or GaN device is pin-compatible.
Frequently Asked Questions
Is the EPC2361 or ADI LT7930 newly available?
EPC announced the EPC2361-based evaluation design on October 20, 2026 and says EPC2361 is offered through its global distribution network. ADI lists LT7930 as recommended for new designs. These statements do not guarantee a particular quantity or delivery date; request current, dated quotations.
Does the 4 kW reference design indicate a GaN shortage or price increase?
No. The October 20 announcement reports an engineering reference design and performance results, not an allocation, price increase, end-of-life notice, or verified MPN-specific shortage.
Can the evaluation board efficiency be used as a production guarantee?
No. The reported typical efficiency is tied to the specified reference-design operating conditions. Engineers must verify performance across the actual load, temperature, PCB layout, thermal design and EMI requirements.
Which exact parts should be listed on the RFQ?
Include the EPC2361 100 V GaN FET and the exact required ADI LT7930 orderable suffix, plus EVAL-LT7930-AZ if an evaluation board is required. Check the latest BOM, revisions and approved alternates before ordering.
