Overview
The LT1308AIS8#PBF is a micropower, fixed-frequency step-up DC/DC converter manufactured by Analog Devices Inc. It operates over an input voltage range of 1V to 10V and provides a single adjustable output ranging from 1.22V to 34V. The device supports a switch current of 2A and functions at a switching frequency of 600kHz. It utilizes an 8-pin SOIC package with a width of 3.90mm. The component is RoHS compliant and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Features automatic shifting to power saving Burst Mode operation at light loads for enhanced efficiency.
- Supports boost and SEPIC topologies for flexible step-up and step-down/buck-boost applications.
- Includes integrated soft-start functionality to limit inrush current during startup.
Applications
- Li-Ion battery powered systems requiring stable 5V or higher outputs
- Portable devices utilizing single-cell lithium batteries
- General purpose micropower step-up conversion in space-constrained designs
Procurement Notes
Verify the specific suffix #PBF indicates lead-free (Pb-free) packaging compliant with RoHS standards. Confirm the 'I' grade designation matches required operating temperature ranges. Ensure the SOIC-8 package dimensions align with PCB footprint requirements. Cross-reference datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring high efficiency at light loads due to its Burst Mode capability. The 600kHz switching frequency allows for smaller external inductors compared to lower frequency alternatives. Consider the 2A switch current limit for load requirements. The adjustable output voltage range up to 34V offers flexibility for various rail generation needs without changing the core controller.
Part Context
This part belongs to the LT1308 family of micropower switching regulators. The LT1308 series is designed for battery-powered applications where low quiescent current is critical. The 'A' grade typically denotes extended temperature performance or tighter electrical tolerances compared to standard grades, while the S8 package identifies the surface-mount SOIC form factor.
Replacement Considerations
LT1308BCS8#PBF: Standard grade version with similar electrical characteristics but potentially different temperature ratings. LT1308IS8#PBF: Industrial grade variant. Verify if the 'A' grade specific parameters are strictly required or if standard industrial equivalents suffice for the application environment.
