Procurement Notes

Verify the specific suffix BPAT2G against official ABLIC documentation to confirm packaging and tape specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Check for any recent Product Change Notifications (PCN) regarding marking or material changes. Ensure the source provides valid traceability for this discontinued or limited-stock component.

Selection Notes

Select this component when a fixed-frequency buck controller with enable functionality is required. The 60kHz switching rate suits applications where moderate efficiency and reduced external component size are prioritized over ultra-low noise. Verify that the input voltage stays within the 2.5V to 16V operational window. Consider the SOT-23-5 footprint constraints during PCB layout design.
