LT1613CS5#TRPBF

Overview

The LT1613CS5#TRPBF is a synchronous step-up, flyback, and SEPIC DC-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range from 0.9V to 10V and provides an adjustable output voltage between 1.23V and 34V. The device supports a maximum switch current of 550mA and functions at a switching frequency of 1.4MHz. It is housed in a TSOT-23-5 package and is rated for operation within a temperature range of 0°C to 70°C.

Feature Summary

Supports boost, flyback, and SEPIC topologies for flexible power conversion
Operates from low input voltages starting at 0.9V
Provides adjustable output voltage up to 34V
Integrated synchronous rectification for improved efficiency

Applications

Battery-powered portable devices requiring wide input voltage ranges
Industrial systems utilizing flyback or SEPIC configurations
Applications needing high-efficiency step-up conversion from single-cell sources

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the TSOT-23-5 footprint matches your PCB design constraints. Ensure the application circuit supports the required input voltage range of 0.9V to 10V. Check thermal management requirements for the small outline package under maximum load conditions.

Selection Notes

Select this component when a compact solution for boost, flyback, or SEPIC conversion is needed. It is suitable for designs requiring operation from very low input voltages down to 0.9V. The integrated synchronous rectifier makes it efficient for moderate current applications up to 550mA. Consider the TSOT-23-5 package size for space-constrained layouts.

Part Context

This part belongs to the LT1613 family of micropower switching regulators. It is designed for applications requiring high efficiency in small packages. The device integrates a 1.4MHz oscillator and synchronous rectifiers to minimize external component count. It is commonly used in portable electronics and industrial sensors where battery life and board space are critical.
