LT1308AIS8#TRPBF

Overview

The LT1308AIS8#TRPBF is a high-current boost and SEPIC DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1V to 10V and provides an adjustable output voltage from 1.22V up to 34V. The device supports a switch current of 2A and functions at a fixed switching frequency of 600kHz. Packaged in an 8-SOIC surface-mount case, it is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Supports both boost and SEPIC topologies for flexible power conversion
• Capable of delivering high output current via integrated 2A switch
• Enables wide input voltage compatibility starting from 1V

Applications

• Single-cell battery charging systems
• Portable instrumentation power supplies
• Industrial sensor node power management

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the 'A' grade designation meets required performance specifications for your application environment. Ensure the SOIC-8 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high efficiency from low-voltage sources like single lithium cells. The adjustable output allows customization for various load requirements without changing the core regulator. Consider the 600kHz frequency for balancing component size against electromagnetic interference levels in sensitive environments.

Part Context

This part belongs to the LT1308 family of high-current switching regulators designed for space-constrained applications. It integrates the power switch and control logic into a compact package, reducing external component count compared to discrete solutions. The series is commonly used in portable electronics where battery life and physical size are critical design parameters.
