Overview
The LT1306ES8#PBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates in a boost topology with a fixed switching frequency of 300 kHz. The device accepts an input voltage range from 1.8 V to 7 V and provides a regulated output voltage of 5.5 V. It supports a maximum output current of 2 A. Key electrical specifications include a quiescent current of 160 uA and an operating temperature range from -40°C to +85°C. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Micropower operation with low static current consumption
- Fixed 300 kHz switching frequency for external component optimization
- Integrated shutdown control for power management
- Single-output boost converter topology
Applications
- Battery-powered portable devices requiring voltage step-up
- Systems generating 5V output from single-cell lithium-ion sources
- Applications converting multi-cell battery packs to regulated 5V rails
- General-purpose DC-to-DC conversion in space-constrained designs
Procurement Notes
Verify the specific suffix ES8#PBF against official Analog Devices documentation to confirm the SOIC-8 package and lead-free compliance status. Confirm availability through authorized distributors as supply may be limited. Ensure the ordering information matches the exact part number variant required for your design, as suffixes denote package type and environmental compliance. Cross-reference datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.
Selection Notes
Select this component when a fixed 300 kHz boost converter is required with high efficiency and low quiescent current. It is suitable for designs needing up to 2 A output current from input voltages between 1.8 V and 7 V. Consider the SOIC-8 package constraints and thermal performance for your PCB layout. Verify that the fixed frequency aligns with your EMI requirements and inductor selection capabilities compared to adjustable frequency alternatives.
Part Context
The LT1306 belongs to Analog Devices' family of micropower step-up DC/DC converters. It is designed for applications where battery life is critical due to its low standby current. The ES8#PBF designation specifically identifies the SOIC-8 package version with Pb-free finish. This part serves as a solution for boosting low input voltages to standard logic levels like 5V in portable electronics.
Replacement Considerations
Consult Analog Devices official substitution guides for verified equivalents. No public substitute part numbers are confirmed in the provided source material.
