Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix D indicates the TSSOP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life or non-recommended-for-new-designations as availability may be restricted. Ensure design-in reviews account for the humidity sensitivity classification indicated in the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution with minimal external parts is required for boost conversion. The TSSOP-8 package suits applications where board space is limited compared to larger packages. Consider the variable frequency operation if electromagnetic interference filtering needs to be spread across a wider spectrum. Validate that the 0.6 V minimum operating voltage aligns with the lowest expected battery discharge curve.

Voltage Regulators - DC DC Switching Regulators Part Context

The L6920D belongs to the L6920 series of power management ICs from STMicroelectronics. This family focuses on high-efficiency DC-to-DC conversion for mobile and portable electronics. The D suffix specifically denotes the TSSOP-8 surface-mount package, distinguishing it from other variants like the DB (MSOP-8) which may have different thermal or pin-out characteristics.
