Overview
The LT1308BCF#TR 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 features a positive adjustable output configuration. The device integrates a 2A power switch and functions as a boost or SEPIC regulator. It utilizes a 14-TSSOP surface-mount package with a width of 4.40mm. The switching frequency is fixed at 600kHz. The minimum output voltage is adjustable down to 1.22V. This component is classified under PMIC - DC DC Switching Regulators.
Feature Summary
- Integrates a high-current 2A power switch for efficient energy transfer
- Supports both step-up and step-up/down (SEPIC) conversion topologies
- Operates with a wide input voltage range from 1V to 10V
- Features micropower operation suitable for battery-powered applications
Applications
- Portable instrumentation requiring single-cell battery operation
- Systems needing voltage boosting from low input sources
- Applications utilizing SEPIC topology for varying input voltages
- Battery-powered handheld devices and sensors
Procurement Notes
Verify the specific suffix #TR indicates tape and reel packaging when ordering. Confirm the BC grade designation matches required performance specifications. Ensure the 14-TSSOP footprint aligns with PCB design constraints. Cross-reference the manufacturer part number LT1308BCF#TR with official Analog Devices documentation to confirm current availability and datasheet revisions before finalizing procurement.
Selection Notes
Select this component when a wide input voltage range up to 10V is required alongside a high-output current capability of 2A. The fixed 600kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the TSSOP package size for space-constrained designs. Verify that the adjustable output range starting at 1.22V meets the target load requirements.
Part Context
The LT1308BCF#TR belongs to the LT1308A/LT1308B family of micropower DC/DC converters. These devices are improved versions designed for single-cell battery applications. The family includes variants with different packaging options such as leaded and tape-and-reel configurations. The BC grade typically denotes specific temperature and performance characteristics within the product line.
Replacement Considerations
LT1308BCF#PBF serves as a leaded alternative in the same package type. LT1308ACF#TR and LT1308BCF#TRPBF are related variants within the series. Verify pin compatibility and electrical parameters before substituting with other models in the LT1308 family.
