SM
SM power management ICs in stock at YILUDA TECH. 70 SM part numbers are held as 100% original, new and unused material — display power management, PMIC and voltage regulation devices in QFN, WLCSP and BGA packages.
What we carry
- Display power management — SM3080, SM3011 and SM4047D devices in WLCSP and QFN, used to generate the rails a panel needs from a single supply.
- Power management and voltage regulation — SM4065, SM4061, SM4057 and SM4006 series in QFN packages.
- PMIC — VPMS3SM in QFN-72 for multi-rail system power sequencing.
- BGA and WLCSP ICs — SM5903, SM5360 and SMA1502-F where board area is the constraint.
- Interface devices — SM4500 isolated RS-485 transceivers in DFN-16.
Most lines are supplied in QFN, which means thermal pad soldering and reflow profile matter — the package is stated on each part number.
Where these parts are used
These devices are typically designed into LCD modules, handheld terminals, set-top and display boards, and compact power trees where a single chip has to sequence several rails.
Ordering notes
- SM codes are suffix-sensitive; the letter after the base number often selects output voltage or package, so send the full code.
- If you are replacing an obsolete SM device, send the original code and the rail it drives and we will check for a form-fit-function alternative in stock.
- Ships worldwide from Shenzhen by DHL, FedEx or UPS.
Questions buyers ask
Can you confirm the output voltage of an SM40xx part?
Yes — send the full ordering code and we will confirm the specification against the datasheet with your enquiry.
Do you supply SM parts in tape and reel?
Packing depends on the specific part; state the quantity you need and we will confirm what is available.
