LT1308BCF#TRPBF

Overview

The LT1308BCF#TRPBF is a high-current, micropower single-cell DC/DC converter manufactured by Analog Devices Inc. It functions as a boost and SEPIC switching regulator IC with positive adjustable output voltage ranging from 1.22V to 34V. The device supports a maximum switch current of 2A and operates at a fixed switching frequency of 600kHz. It accepts an input voltage range between 1V and 10V. The component is housed in a 14-TSSOP package with a width of 0.173 inches (4.40mm). It is designed for operation within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated boost and SEPIC topology for flexible step-up or step-down/buck-boost applications
• Micropower quiescent current design optimized for single-cell battery efficiency
• High current capability with 2A switch current rating for demanding load requirements

Applications

• Portable handheld devices requiring efficient power management from single-cell sources
• Battery-powered systems utilizing boost or SEPIC conversion topologies
• Applications requiring compact solutions for voltage regulation in space-constrained environments

Procurement Notes

Verify the specific suffix CF indicates the 14-TSSOP package configuration distinct from other variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified operating temperature range. Cross-reference pinouts with the official datasheet to prevent layout errors during PCB design implementation.

Selection Notes

Select this variant when a 14-pin TSSOP footprint is required instead of the SOIC option. Choose based on the need for integrated SEPIC functionality alongside standard boost capabilities. Consider the 600kHz switching frequency for balancing component size against transient response needs. Validate that the 1V minimum input voltage meets the lowest expected source level.

Part Context

This component belongs to the LT1308 series of high-current, micropower DC/DC converters. The series includes variants such as LT1308AIS8 and LT1308BCS8, which differ primarily in package type and performance grades. The LT1308 family is engineered for single-cell lithium-ion or alkaline battery applications where efficiency and low standby current are critical.

Replacement Considerations

LT1308BIS8#TRPBF is documented as a parameter-equivalent substitute.
