LT1305CS8#TRPBF

Overview

The LT1305CS8#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It utilizes Burst Mode operation and features an internal low-loss switch capable of delivering up to 2.5A output current. The device provides a fixed positive output voltage of 5V in a single-output configuration. It operates within an input voltage range of 1.5V to 8V and supports a switching frequency of 300 kHz. The component is housed in an 8-SOIC package with a width of 3.90mm, designed for surface mount technology applications.

Feature Summary

• Integrates a high-power internal switch for efficient energy transfer
• Employs Burst Mode operation to minimize quiescent current consumption
• Includes a low-battery detector function for system monitoring

Applications

• Portable battery-powered equipment requiring efficient voltage boosting
• Systems utilizing lithium-ion or alkaline battery sources
• Applications necessitating low standby power consumption

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check for RoHS compliance documentation as required by your assembly standards. Ensure the SOIC-8 footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from variable low-voltage inputs. Consider the 2.5A switch capability against your peak load demands. Evaluate the 300 kHz switching frequency for EMI compatibility with surrounding circuitry. Compare the micropower characteristics against other boost converters if extended battery life is a primary design constraint.

Part Context

This part belongs to the LT1305 series of micropower step-up DC/DC converters. It shares functional similarities with the LT1303 but offers higher current capabilities. The series is characterized by its ability to operate efficiently at low input voltages while maintaining stable output regulation under varying load conditions.

Replacement Considerations

LT1305CS8#PBF is a leaded alternative offering identical electrical performance in a non-surface-mount package.
