LT1615IS5-1#TRPBF

Overview

The LT1615IS5-1#TRPBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1V to 15V and provides an adjustable output voltage from 1.23V to 34V. The device supports Boost and SEPIC topologies, delivering up to 75mA of switch current in a TSOT-23-5 package. It features a low quiescent current of 20µA and includes a shutdown function for power conservation. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Supports both Boost and SEPIC conversion topologies for flexible voltage regulation
• Integrates a shutdown pin to minimize standby power consumption
• Operates efficiently with a single-cell lithium-ion or alkaline battery source

Applications

• Portable electronic devices requiring high efficiency from single-cell batteries
• Battery-powered instrumentation systems
• Applications needing negative voltage generation via SEPIC configuration

Procurement Notes

Verify the specific suffix '#TRPBF' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the 'I' grade designation matches the industrial temperature range specifications for your operational environment. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm RoHS compliance and material declarations prior to final procurement authorization.

Selection Notes

Select this component when designing circuits that require a compact solution for stepping up low input voltages to higher levels. The adjustable output allows customization for various load requirements within the specified limits. Consider the thermal performance in the TSOT-23-5 package when determining PCB layout constraints for heat dissipation during continuous operation at maximum load currents.

Part Context

This part belongs to the LT1615 family of micropower switching regulators designed for space-constrained portable applications. It shares core architecture with other variants in the series but differs in packaging and temperature rating. The IS5-1 designation indicates the industrial temperature grade and specific pinout configuration compatible with standard thin SOT packages used in modern surface-mount designs.

Replacement Considerations

LT1615ES5-1#TRMPBF is a documented alternative offering identical electrical characteristics in a cut-tape package format.
