1A switch and input floor — what they mean for the rail budget
The 1A switch current rating sets the maximum inductor peak current the internal power FET can handle.
Switching frequency and inductor sizing
The 260kHz to 340kHz switching range is on the lower side for modern boost converters.
Lifecycle and compliance
It is ROHS3 compliant. No official second-source or pin-compatible alternate is listed in the available records, so dual-sourcing would require a separate qualification effort. For current pricing and availability, submit an RFQ — the part is sourced through independent distribution and quoted to order.
