Microchip 20A GaN POL Converter Enters Production Supply: POL-05-20S-T Buyer Checklist
A sourcing-focused update on Microchip's radiation-tolerant GaN point-of-load converter for demanding digital power rails. The manufacturer's October 14 announcement identifies POL-05-20S-T and states that production quantities are available. This October 19 briefing reviews confirmed specifications and the checks buyers should make before issuing an RFQ.
Confirmed Technical and Commercial Details
- Orderable model: POL-05-20S-T, a GaN-based radiation-tolerant point-of-load (POL) DC-DC converter.
- Current capability: up to 20 A continuous output current.
- Electrical ranges: 4.75–13.2 V input; adjustable 0.7–5 V output.
- Package: surface-mount, approximately 1.51 × 1.51 × 0.45 inches; manufacturer states a mass of 25 g.
- Radiation data: electrical characteristics specified before and after total ionizing dose exposure up to 50 krad; single-event effects characterized to LET 43 MeV·cm²/mg.
- Operating conditions: −55°C to +100°C at full load, according to the manufacturer.
- Availability statement: Microchip says production quantities are available through direct and authorized channels. Actual delivery date, price and quantity for a specific buyer must be reconfirmed at quotation.
Why Buyers Should Pay Attention
The announced part targets compact high-current rails supplying FPGAs, MCUs, ASICs and other processing-intensive loads in demanding environments. For a qualified design, integrating a high-current POL converter may affect power-stage footprint, thermal design, transient response and approved-vendor planning. It should not be treated as a drop-in substitute for a conventional commercial buck regulator without electrical, mechanical and reliability review.
Procurement Signal Classification
Confirmed: product identity, published electrical/radiation specifications and manufacturer's statement of production-quantity availability.
Not confirmed: live distributor inventory, guaranteed lead time, customer-specific qualification, price movement, allocation status or any broad shortage affecting GaN converters.
Market interpretation: one additional high-reliability GaN power option; no evidence from this announcement alone of an industry-wide GaN supply shift.
RFQ and Qualification Checklist
- Specify the exact manufacturer part number POL-05-20S-T, required quantity, delivery destination and requested date; do not substitute based on the headline current rating alone.
- Confirm input/output rails, full-load current, transient response, thermal constraints, mounting and test conditions against the current datasheet.
- For mission-critical applications, request applicable screening, traceability, lot documentation, radiation characterization and qualification records from the manufacturer or approved channel.
- Ask for a dated stock/lead-time quotation and applicable export-control, end-use and end-user review before committing to shipment.
- For alternative BOM candidates, compare actual qualification and system-level requirements, not just nominal current and voltage ranges.
Frequently Asked Questions
Is POL-05-20S-T already in production?
Microchip's October 14, 2026 release says the converter is available in production quantities. This is the manufacturer's statement; a buyer should still obtain a current quote for the requested lot and destination.
Does the announcement show a shortage or price increase?
No. The release does not announce an allocation, EOL, shortage or price increase. A live RFQ is required to determine actual commercial terms.
Can a standard 20A POL regulator replace it?
Not by current rating alone. Designers must evaluate electrical, thermal, radiation, reliability and qualification requirements before approving any substitution.
