Creating search plan for: "buck-boost converter 3.3V 500mA load quiescent <1uA single-cell Li-ion to 3.3V, ultra-low quiescent current for battery IoT, PFM/burst acceptable, small footprint preferred"

Searching: "A generic buck-boost switching regulator aimed for battery-powered IoT applications. Looking for a part that steps up/down a single-cell Li-ion voltage to 3.3V with a load capability of 500mA. Focus on low quiescent current design (<1µA) and acceptance of PFM/burst mode with a compact footprint."

Searching: "A 3.3V buck-boost converter suitable for single-cell Li-ion battery applications, capable of delivering up to 500mA load current. The part must feature ultra-low quiescent current (<1µA) and support pulse frequency modulation (PFM) or burst operation, emphasizing high efficiency and small PCB footprint for IoT devices."

Searching: "A buck-boost converter developed for battery-driven IoT platforms, prioritizing ultra low standby/quiescent current (<1µA) alongside a 3.3V output and 500mA load capacity. Must function well in PFM mode or burst mode with a minimized footprint to extend battery life in compact devices."

Searching: "A highly efficient buck-boost regulator with PFM operation for ultra low power battery IoT applications. Key specifications include single-cell Li-ion input, 3.3V output, maximum load of 500mA, and quiescent current less than 1µA. Small physical size is required for tight PCB layouts."

Here are the closest matches I found for “buck-boost, 3.3 V, 500 mA, quiescent <1 µA.” Note: the candidates below are 3.3 V/500 mA buck‑boost parts, but sub‑1 µA quiescent current at this load class is uncommon; these typically have higher Iq.

Notes and next steps
  • Ultra‑low Iq (<1 µA) and 500 mA output are a tough combo. Library matches at 500 mA tend to have higher Iq. If <1 µA is a hard requirement, we can either:
    • Reduce the max continuous load target to surface true nanopower buck‑boost options (e.g., search families like TPS63900).
    • Keep 500 mA but relax Iq (e.g., <10–20 µA), which opens many viable 3.3 V buck‑boost choices.
    • Use system power‑gating so the converter sleeps off most of the time, meeting average Iq goals.
  • Preference? I can rerun the search with adjusted constraints or shortlist one of the above to verify Iq from the datasheet.
