LT3500IMSE#TRPBF

Overview

The LT3500IMSE#TRPBF is a monolithic step-down DC/DC converter manufactured by Analog Devices Inc. It integrates a 2.3A internal switch and operates with an input voltage range of 3V to 36V, with a maximum rating of 40V. The device provides a fixed 2A output current capability. It utilizes current mode PWM control architecture for stable regulation. The component is housed in a 16-MSOP package with an exposed pad (EP) for thermal management. It supports switching frequencies up to 2.2MHz and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-current 2.3A internal power switch for compact design
• Supports wide input voltage ranges suitable for industrial and automotive applications
• Includes short-circuit protection across the full operating input range

Applications

• Industrial control systems
• Automotive electronics
• Aerospace equipment

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Linear Technology legacy branding. Ensure the RoHS compliance status matches project requirements. Cross-reference the 16-MSOP-EP package dimensions against PCB footprint specifications. Validate that the 2.2MHz switching frequency aligns with electromagnetic interference constraints.

Selection Notes

Select this component for designs requiring a single-inductor buck solution with high input voltage tolerance. The 2A output current suits moderate power loads without external passives. Consider the 16-MSOP package size for space-constrained layouts. Evaluate thermal performance given the exposed pad requirement for heat dissipation. Compare against alternatives if higher current density or different pinouts are necessary.

Part Context

This part belongs to the LT3500 family of monolithic switching regulators. It is distinct from the LT3501, which offers dual outputs and different current ratings. The IMSE variant specifies the industrial temperature grade and MSOP package. It serves as a direct replacement for older Linear Technology versions with identical electrical characteristics.

Replacement Considerations

LT3500EMSE#PBF is a parameter-equivalent alternative available in tube packaging. Both parts share identical electrical specifications and functionality. Verify package compatibility if transitioning between reel and tube formats.
