Overview
The LT1307IS8#PBF is a micropower, fixed-frequency DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage range of 1V to 5V and provides a single adjustable output ranging from 1.22V to 30V. The device supports a maximum switch current of 600mA and functions as a boost regulator. It utilizes a synchronous rectifier configuration and operates at a switching frequency of 600kHz. The component is housed in an 8-SOIC package with a width of 3.90mm and is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Achieves true current mode PWM performance from a single cell supply
- Features automatic shifting to power saving Burst Mode operation at light loads
- Maintains high efficiency over a broad load range
Applications
- Single cell to 3.3V boost converters
- Low cost 2-cell to 5V PWM converters
- LCD bias generators
- Boost converters with simulated loads
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS status according to manufacturer documentation. Confirm the 8-SOIC package dimensions match the design footprint requirements. Ensure the input voltage range of 1V to 5V aligns with the source circuit. Check the operating temperature range of -40°C to +85°C against environmental specifications.
Selection Notes
Select this component when a micropower solution is required for single or dual-cell battery applications. The adjustable output up to 30V allows flexibility for various load requirements. The 600mA switch current capability supports moderate power needs. Consider the 600kHz switching frequency for balancing component size and efficiency. The Burst Mode feature is advantageous for extending battery life in low-duty-cycle scenarios.
Part Context
The LT1307 series represents a family of micropower DC/DC converters designed for portable electronics. The IS8 variant specifically denotes the industrial temperature grade (-40°C to +85°C) and the SOIC-8 surface mount package. This part is categorized under Switching Voltage Regulators within the Power Management ICs (PMIC) subcategory, distinct from linear regulators or other converter topologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative components from other manufacturers.
