TI Power Management IC Replacement Plan
TPS5430 / TPS54331 / TLV1117-33 → Chipown AP65xx/AP61xx, Silergy SY8120, etc. — full DC-DC/LDO coverage, domestic lead 4–8 weeks, significant cost advantage (quote for latest pricing).
Application Scenario
For power designs using TI buck DC-DC and LDO (servers, comm boards, industrial power, appliances). TI Q3-2026 price hikes (15–85% on power ICs) effective, analog lead times 30–36 weeks, replacement gap 15–30:1.

Core Components
- Chipown AP6500/AP6680 — 5A high-voltage buck, 4.5–40/60V, ESOP-8, targets TPS5430/TPS54560
- Chipown AP6100 — 3A buck, 4.5–40V, SOT-23-6, targets TPS54331
- Chipown APL1117-3.3 — LDO 3.3V/1A, SOT-223
- Silergy SY8120IABC — 2A buck, 4.5–18V, SOT-23-6, targets TPS562201
BOM Notes
- Redesign: reselect by Vin/Iout/package; re-evaluate inductor and feedback network
- LDO class (TLV1117-33→APL1117-3.3) has minimal peripheral changes, low switch risk
- For high-current DC-DC, verify loop stability and ripple first
- TI price hikes in effect — switch by designator in batches and lock domestic long-term supply
Conclusion & Recommendation
Chipown AP65xx targets TI TPS5430/TPS54560 (strong 40–100V wide-input DC-DC), Silergy SY82xx has ample supply. Switch by power tier: LDO first, medium/low-voltage DC-DC in parallel, high-voltage high-current via 4–8 week redesign.
