LT1307IS8#TRPBF

Overview

The LT1307IS8#TRPBF is a micropower, fixed-frequency DC/DC converter manufactured by Analog Devices Inc. It operates from an input voltage as low as 1V and features true current mode PWM performance from a single cell supply. The device automatically shifts to power-saving Burst Mode operation at light loads, maintaining high efficiency over a broad load range of 100 uA to 100mA. It is available in an 8-pin SOIC package.

Feature Summary

• Achieves true current mode PWM performance from a single cell supply
• Features automatic shifting to power saving Burst Mode operation at light loads
• Maintains high efficiency over a broad load range

Applications

• Single cell to 3.3V boost converter circuits
• Low cost 2-cell to 5V PWM converter applications
• LCD bias generator PWM converter designs
• Step-up/step-down converter implementations

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the industrial temperature grade associated with the IS8 variant against system requirements. Ensure compatibility with the 8-SOIC footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any recent design changes or compliance updates before finalizing procurement.

Selection Notes

Select this component for applications requiring efficient power conversion from low-voltage sources like single-cell batteries. The integrated Burst Mode capability makes it suitable for battery-operated devices where standby current consumption is critical. Consider the fixed switching frequency and current mode control architecture for noise-sensitive designs requiring stable regulation across varying load conditions.

Part Context
