LT3976IMSE#TRPBF

Overview

The LT3976IMSE#TRPBF is a monolithic buck switching regulator from Analog Devices, housed in an MSOP-16 package with an exposed pad. It accepts input voltages up to 40V and delivers a continuous output current of 5A. The device features an adjustable switching frequency ranging from 200kHz to 2MHz. It maintains a low quiescent current of 3.3µA and supports a wide output voltage range starting from 1.197V.

Feature Summary

• Integrates a high-current 5A synchronous switch for efficient power conversion
• Features adjustable switching frequency to optimize efficiency and external component size
• Designed with ultra-low quiescent current to minimize standby power consumption

Applications

• Industrial distributed power systems
• Point-of-load regulation modules
• Battery-powered equipment requiring high efficiency

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the IMSE variant corresponds to the industrial temperature range specifications. Ensure compatibility with the MSOP-16 footprint and thermal requirements during procurement planning.

Selection Notes

Select this component for applications requiring high output current within a compact form factor. The adjustable frequency allows optimization for EMI constraints or transient response needs. Verify that the 40V maximum input rating aligns with the system supply rails.

Part Context

This part belongs to the LT3976 family of high-performance buck regulators. It shares architectural similarities with other members like the LT3971 but offers higher current capability. The series is designed for applications demanding robust performance in space-constrained environments.

Replacement Considerations

Direct substitutes include other Analog Devices buck regulators with similar 40V input and 5A output ratings. Verify pinout compatibility and thermal characteristics before replacing with alternative models.
