Procurement Notes
Verify the specific suffix 'DSE' against the official datasheet to confirm the reel quantity and tape configuration. Ensure the component matches the required RoHS compliance status and lead-free specifications for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a fixed 3.3V output is required from a single-cell lithium-ion or lithium-polymer battery source. The low quiescent current makes it suitable for applications requiring long standby times. Consider the WSON-6 package size constraints and thermal requirements during PCB layout to ensure optimal performance.
Part Context
This device belongs to the TPS61098x series of high-efficiency boost converters. It is engineered for space-constrained portable applications where power management efficiency is critical. The series integrates protection features and offers a compact footprint compared to discrete solutions.
Replacement Considerations
Consult the TI product selection guide for direct pin-compatible alternatives within the TPS6109x family. Verify that substitute parts match the output voltage tolerance and current capabilities.
