LT1308BIS8#PBF

Overview

The LT1308BIS8#PBF is a high-efficiency, monolithic boost DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage range of 1 V to 10 V and delivers up to 2 A output current with a maximum output voltage of 34 V. The device integrates a 600 kHz switching frequency and features a low quiescent current of 2.5 mA. Packaged in an SOIC-8 surface-mount format, it supports shutdown functionality and operates within a temperature range of -40°C to +85°C.

Feature Summary

Integrates a high-current switch capable of delivering up to 2 A for efficient power conversion
Features a fixed 600 kHz switching frequency to optimize external component size
Includes a shutdown pin for effective power management and extended battery life

Applications

Single-cell lithium-ion or lithium-polymer battery charging systems
Portable devices requiring step-up conversion from low input voltages
General-purpose boost regulation in space-constrained PCB designs

Procurement Notes

Verify the specific suffix IS8 against the datasheet to confirm package dimensions and thermal characteristics. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm RoHS compliance status through official manufacturer documentation before integration into final assemblies.

Selection Notes

Select this component when designing circuits that require boosting low single-cell battery voltages to higher levels efficiently. The fixed 600 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 2 A current limit and 34 V maximum output voltage when sizing external components for the target application load.

Part Context

This part belongs to the LT1308 family of high-efficiency boost converters. It shares architectural similarities with variants like the LT1308AIS8#TRPBF but differs in packaging and temperature rating specifications. The series is designed for applications demanding compact solutions with high power density from low-voltage sources.
