Procurement Notes
Verify the package type is 20-TSSOP and ensure the operating temperature range meets system requirements of -40°C to 85°C. Confirm that the input voltage range of 2.7V to 5.5V aligns with the source battery configuration. Check for specific ordering suffixes if available, though standard TPS61106PW denotes the base component. Ensure compatibility with PCB layout guidelines for high-frequency switching components.
Selection Notes
Select this component when a dual-output solution is required from a single-cell or dual-cell battery source. The integrated LDO simplifies design by providing a stable auxiliary voltage alongside the boosted main output. Consider the 1.38MHz switching frequency for minimizing external inductor and capacitor sizes. Verify that the thermal performance in the 20-TSSOP package is adequate for the expected load conditions.
Part Context
The TPS61106PW belongs to Texas Instruments' TPS6110x family of dual-output, single-cell boost converters. This series is engineered to provide efficient power conversion for portable applications. The PW suffix indicates the 20-TSSOP package variant. It complements other TPS611xx models by offering integrated regulation capabilities.
Replacement Considerations
Direct substitutes may include other TPS6110x variants with similar pinouts and electrical characteristics. Verify compatibility regarding input voltage range, output currents, and switching frequency before substitution. Consult official datasheets for pin-to-pin compatibility and functional equivalence.
