LT1613CS5#TRM

Overview

The LT1613CS5 is a 1.4MHz single-cell DC/DC converter housed in a 5-lead SOT-23 package. It functions as a boost or inverting converter with an integrated 2A switch, soft-start capability, and synchronization feature. The device operates with an input voltage range of 1V to 6V. It provides regulated output voltages of 3.3V at 0.13A or 5V at 0.12A. This component is designed for efficient power conversion in space-constrained applications.

Feature Summary

• Integrates a high-current 2A internal switch for robust power handling
• Features built-in soft-start to limit inrush current during startup
• Supports external synchronization to reduce system noise
• Operates from a single cell battery source

Applications

• Portable electronic devices requiring single-cell power sources
• Battery-powered instrumentation systems
• Space-constrained embedded power solutions

Procurement Notes

Verify the specific suffix TRM indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation corresponds to Linear Technology or its successor Analog Devices. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component for designs requiring a compact footprint due to the SOT-23 package. It is suitable for applications needing a fixed 1.4MHz switching frequency. Consider the 2A switch current limit when sizing external inductors. Verify that the required output voltage aligns with standard configurations supported by the device architecture.

Part Context

This part belongs to the LT1613 family of single-cell DC/DC converters. It shares functional similarities with other Linear Technology power management ICs designed for portable electronics. The series emphasizes efficiency and small size, targeting mobile and battery-operated markets where board space is limited.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Evaluate similar boost converters with comparable current ratings and switching frequencies. Ensure any substitute maintains the required input voltage range and package dimensions for mechanical compatibility.
