LT3460EDC-1#TRMPBF

Overview

The LT3460EDC-1#TRMPBF is a switching voltage regulator manufactured by Analog Devices Inc., housed in a 6-WFDFN (DFN) package with an exposed pad. It operates as a boost or SEPIC DC/DC converter with a switch current rating of 180 mA. The device supports an input voltage range from 2.5 V to 16 V and provides an adjustable output voltage up to 36 V. It features selectable switching frequencies of 650 kHz or 1.3 MHz, a shutdown pin for power management, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports both boost and SEPIC topologies for flexible step-up or step-up/step-down conversion
• Features selectable switching frequencies of 650 kHz or 1.3 MHz to optimize external component size
• Includes a shutdown control pin for efficient power management

Applications

• Portable battery-powered equipment requiring step-up conversion
• Systems utilizing single-cell lithium-ion batteries
• General purpose DC/DC conversion in space-constrained designs

Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and DFN-6 enclosure details. Confirm availability status through authorized distributors, as supply may be restricted. Ensure compatibility with required input/output voltage ranges and thermal performance specifications before integration.

Selection Notes

Select this component when a compact solution for boosting or SEPIC conversion is required. The choice between 650 kHz and 1.3 MHz frequencies allows optimization of inductor and capacitor sizes based on board space constraints. Verify that the 180 mA switch current meets load requirements and that the 2.5 V to 16 V input range aligns with the source voltage.

Part Context

This part belongs to the LT3460 family of high-efficiency switching regulators designed for small form-factor applications. The DFN-6 package minimizes footprint, while the dual-frequency option provides design flexibility. It serves as a versatile power management solution for portable electronics where space and efficiency are critical.

Replacement Considerations

Check for direct substitutes within the LT3460 series or other Analog Devices boost/SEPIC regulators with similar current ratings and packages. Verify pinout compatibility and electrical parameters such as switching frequency and input voltage range before substitution.
