MIC28517T-E/PHA

Microchip Technology

The MIC28517T-E/PHA is a Microchip Technology 70 V, 8 A Hyper Speed Control synchronous buck regulator in a 32-pin 6 mm by 6 mm VQFN. Its 4.5 V to 70 V input range and adjustable 0.6 V to 32 V output with +/-1 percent feedback accuracy cover 12 V, 24 V and 48 V industrial and telecom rails from a single device, which consolidates inventory and simplifies platform power design. The adaptive on-time architecture gives ultra-fast transient response with small output capacitance, and a pin-selectable HyperLight Load or forced continuous-conduction mode keeps light-load efficiency high. Adjustable 270 kHz to 800 kHz switching, internal compensation, a built-in 5 V regulator, auxiliary bootstrap LDO, programmable current limit, hiccup short-circuit protection and thermal shutdown reduce external component count and protect the load, supporting safe start-up into a pre-biased output. It operates from -40C to +125C junction temperature. Selection advice: this variant carries the MODE pin for HLL versus CCM selection; if your design instead needs an externally adjustable soft-start time, choose its sibling MIC28516, which trades the MODE pin for a soft-start pin.

SELECTION GUIDANCE

MIC28517T-E/PHA selection guidance

MIC28517T-E/PHA is a Synchronous buck converter from Microchip Technology, orderable in the VQFN-32 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

MIC28517T-E/PHA FAQ

What do the suffixes in MIC28517T-E/PHA mean?

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. MIC28517T-E/PHA names the VQFN-32 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for MIC28517T-E/PHA?

The package (VQFN-32) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.

Can you provide traceability documents for MIC28517T-E/PHA?

Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.

How do I request a quotation for MIC28517T-E/PHA?

Add MIC28517T-E/PHA to your RFQ with the complete ordering code, the manufacturer (Microchip Technology), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
