52-week lead times are here for many STM32 microcontroller families. ⏳

STMicroelectronics has asked distributors to lock in customers’ full-year 2027 orders, and supply is tightening across Infineon and NXP lines too. One missing MCU can stall an entire build.

Our new blog breaks down what’s driving the delays and how engineering and procurement teams can protect production through 2027.

LDO or switching regulator? 🔋⚡

It’s one of the most common decisions in power design, and the right answer depends on your priorities.

🔵 LDOs: low noise, simple, ideal for clocks, ADCs, and sensors
🟠 Switchers: 85–95% efficiency, perfect for high-current and battery-powered designs
🔀 Hybrid: a buck converter followed by an LDO gives you efficiency and clean power

Our new guide breaks down the trade-offs in efficiency, heat, noise, EMI, and cost, plus a practical framework for choosing the right topology.

Is your power rail actually ready? ⚡

A power good (PGOOD) signal tells downstream chips when a supply is stable and in spec, so processors, FPGAs, and MCUs don’t boot on shaky voltage.

Our new blog breaks down:
✅ How PGOOD thresholds and delay timers work
✅ Using PGOOD for power sequencing and fault detection
✅ Open-drain vs. push-pull outputs
✅ Common design mistakes to avoid

Wrong rail order, wrong results. ⚡

In multi-rail designs, the order your voltage rails power up (and down) matters. Get it wrong and you risk latch-up, stressed silicon, and boards that won’t boot.

Our new Power Sequencing 101 guide covers:
🔹 What goes wrong when sequencing is ignored
🔹 Discrete RC delays vs. PGOOD daisy chains vs. power sequencing ICs
🔹 Why shutdown order deserves as much attention as startup
🔹 A design checklist for your next multi-rail board

🎉 Happy 18th Workiversary to the legendary Ryan Berger! 🎉

Eighteen years is an incredible achievement! Even though he recently traded his local spot for Idaho (and yes, we miss him around the office!), Ryan is still a huge part of the Suntsu family. He’s known for his deep industry knowledge AND his ability to keep us all smiling with a perfectly timed dad joke 😂.

Thanks for always going above and beyond and for being such an awesome mentor. Here's to many more years of success (and more jokes across state lines)! Congratulations, Ryan! 🙌

🎉 Seventeen years for the one and only Robert Rangel! 🎉

Robert brings the energy every single day—whether he's dominating at the foosball table ⚽, dropping a quick, hilarious one-liner, or just generally being a legend! Thanks for always pushing us to be our best and for the non-stop laughs over the last 17 years, Robert! Here's to many more years of wins and wisdom! 🙌

✨ Happiest of belated work anniversaries to Kassidy Farina as she celebrates 5 years with Suntsu! 🎉

Kassidy is our Supply Chain Specialist extraordinaire, keeping everything flowing like magic! 🪄 When she's not orchestrating logistics, she's probably planning her next Disney adventure—our ultimate resident Disney fanatic! 🏰 Thanks for bringing your dedication and sparkle to the team for half a decade, Kassidy! Here's to many more! 🥂✨

Is hidden DRAM refresh power draining your battery budget? 🔋

While active read and write operations get all the attention during power modeling, background refresh cycles quietly draw continuous baseline current. At higher operating temperatures, dynamic memory cells leak charge exponentially faster, forcing refresh rates to double and driving standby power through the roof.

See how auto-refresh, self-refresh, and Partial-Array Self-Refresh (PASR) compare, and read our full technical breakdown at the link in our bio!

When a critical memory IC goes end-of-life, finding drop-in replacements quickly is essential to keep production moving.

Fab capacity shifts are forcing mature memory chips into obsolescence faster than ever. Check out our newest article to learn how engineering and procurement teams identify warning signs early, qualify Form-Fit-Function equivalents, and verify legacy inventory.
