LT1613CS5#TR

Overview

The LT1613CS5#TRMPBF is a synchronous step-up DC-DC converter IC manufactured by Analog Devices Inc. It operates with an input voltage range of 0.9V to 10V and provides an adjustable output voltage up to 34V. The device features a fixed switching frequency of 1.4MHz and supports boost, flyback, and SEPIC topologies. It delivers a switch current capability of 550mA in a TSOT-23-5 package.

Feature Summary

Supports multiple conversion topologies including boost, flyback, and SEPIC configurations.
Operates at a high switching frequency of 1.4MHz for compact passive component sizing.
Features synchronous rectification for improved efficiency.

Applications

Uncoupled SEPIC circuit implementations
Boost DC-DC conversion applications
Flyback converter designs

Procurement Notes

Verify the complete part number includes the suffix #TRMPBF for tape and reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the datasheet matches the specific electrical characteristics required for the target application design.

Selection Notes

Select this component for applications requiring flexible topology support such as SEPIC or flyback within a small SOT-23 footprint. Consider the 1.4MHz switching frequency for size constraints and the 0.9V minimum input voltage for battery-powered systems. Verify thermal performance requirements for the TSOT-23-5 package under expected load conditions.

Part Context

This component belongs to the LT1613 family of synchronous step-up converters. It is designed for space-constrained portable electronics requiring efficient power management from single-cell lithium-ion batteries or other low-voltage sources.
