Procurement Notes

Verify the specific package variant (WLCSP vs DFN) against the official datasheet, as sources indicate multiple physical form factors for this part number. Confirm the exact output voltage tolerance and thermal performance specifications required for your design before ordering. Ensure compatibility with the manufacturer's recommended layout guidelines for optimal efficiency.

Selection Notes

Select this component when designing circuits powered by low-voltage energy harvesters such as thermoelectric generators or solar cells. The wide input range starting at 350mV makes it suitable for scavenging energy from weak sources. Consider the 2.6V fixed output when matching downstream load requirements.

Part Context

This part belongs to the R1810x series of non-isolated DC-DC converters. It is categorized under PMIC - Power Management ICs. The series is characterized by its ability to operate with very low input voltages, targeting applications where standard regulators cannot function due to insufficient supply headroom.
