TI TPS62913 Shortage Replacement Plan
TI official site confirms TPS62913RPUR OutOfStock (day 12) → Chipown AP65xx/AP66xx redesign (4–8 wks) as priority, TPS62912 (2A pin-to-pin sibling) for emergency, 411 pcs LCSC stock lockable.
Application Scenario
For 17V-in, 3A-out low-noise low-ripple buck applications (FPGA/SoC core supply, server/comm boards, instruments). TI official marks OutOfStock and international channels have zero real chips — notify customers with in-flight orders and start domestic replacement now.
System Diagram
Placeholder: 17V input → buck converter (TPS62913RPUR or Chipown AP65xx/AP66xx redesign) → 3A/2A output; inductor and feedback network per selection. TPS62912 is the 2A pin-to-pin emergency option. Full schematic in preparation — contact us.
Replacement Matrix
| Option | Part | Status | Timeline / Cost |
|---|---|---|---|
| Emergency (≤2A) | TPS62912 (TI) | TI official ACTIVE | Available now |
| Redesign priority | Chipown AP65xx / AP66xx | Domestic stock in transit | Redesign 4–8 wks |
| Backup | Silergy SY82xx | — | Redesign 4–8 wks |
Core Components
- TPS62913RPUR — VQFN-HR (RPU) 10-pin, 17V/3A buck, currently OutOfStock on TI official
- TPS62912 — 2A pin-to-pin compatible sibling (emergency)
- Chipown AP65xx / AP66xx — domestic buck family (preferred redesign)
BOM Notes
- TPS62912 emergency: pin-to-pin swap — verify current margin (≤2A) and ripple spec
- Chipown redesign: reselect by Vin/Iout/package; re-evaluate inductor and feedback network
- LCSC emergency lock: exact-term TPS62913RPUR stock 411 pcs — lock what can be ordered
Conclusion & Recommendation
TI official confirms no stock — start replacement immediately (Chipown AP65xx/AP66xx redesign 4–8 wks); audit in-flight customer orders and notify; switch to TPS62912 first if current need is ≤2A; re-check international channels on 8/24.
