- Positive adjustable output voltage configuration
- Compact TSOT-23-6 thin package design
Applications
- Battery-powered portable electronics
- General DC-DC step-up conversion circuits
- Embedded systems requiring regulated power rails
Procurement Notes
Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and pin alignment against the official datasheet specifications prior to integration. Ensure supply chain documentation matches the manufacturer product number exactly to avoid counterfeit risks associated with discontinued semiconductor inventory.
Selection Notes
Select this component when a compact boost regulator with 850mA capability is required. The TSOT-23-6 package suits space-constrained designs. Verify that the input voltage range of 0.85V to 5V aligns with the source supply. Consider the 1.2MHz switching frequency for inductor size trade-offs relative to lower-frequency alternatives.
Part Context
This part belongs to the AS1329 series of DC-DC switching regulators. It shares functional similarities with the AS1329A-BTTT variant but may differ in specific electrical tolerances or packaging suffixes. The series targets low-power boost applications requiring high efficiency in small footprints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's obsolescence notices or technical support for qualified replacement recommendations.
