LT1317IS8#TRPBF

Overview

The LT1317IS8#TRPBF is a high-efficiency, monolithic switching regulator manufactured by Analog Devices Inc. It operates as a boost converter with an integrated 500mA switch and a fixed 600kHz PWM frequency. The device supports input voltages from 1.5V to 12V and delivers up to 30V output. It features a shutdown mode reducing quiescent current to 100µA. Packaged in SOIC-8 for surface mount applications, it functions within a temperature range of 0°C to +70°C.

Feature Summary

• Integrates a 500mA power switch with a fixed 600kHz PWM controller for compact design
• Provides efficient step-up voltage conversion from low input sources
• Includes a shutdown pin to minimize standby power consumption

Applications

• Portable instrumentation requiring extended battery life
• Single-cell or multi-cell battery-powered systems
• General-purpose DC/DC conversion in space-constrained designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IS8 variant meets industrial temperature specifications if operating conditions exceed standard commercial ranges. Cross-reference the manufacturer datasheet to ensure compatibility with required input voltage levels and load currents before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a simple boost topology with moderate current demands. Ensure the external inductor and diode ratings support the 500mA internal switch limit. Consider thermal management requirements given the SOIC-8 package size and potential power dissipation during continuous operation at higher duty cycles.
