LT3976IMSE#PBF

Overview

The LT3976IMSE#PBF is a monolithic buck switching regulator from Analog Devices, housed in an MSOP-16 package. It supports 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 incorporates a low quiescent current design with a typical value of 3.3µA. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-current 5A synchronous buck topology for efficient power conversion.
• Features an adjustable switching frequency allowing optimization for size or performance.
• Designed with ultra-low quiescent current to minimize standby power consumption.

Applications

• Industrial point-of-load regulation
• Battery-powered equipment power management
• Embedded system voltage step-down

Procurement Notes

Verify the specific suffix #PBF confirms lead-free packaging compliance when sourcing. Confirm the MSOP-16 package variant matches thermal requirements. Cross-reference the manufacturer part number directly with official Analog Devices documentation to ensure authenticity. Validate that the operating temperature range meets the specific application environment constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring high output current from a moderate input voltage source. The adjustable frequency allows trade-offs between external component size and efficiency. Ensure the thermal design accommodates the power dissipation inherent in the MSOP-16 package. Verify that the required output voltage falls within the adjustable range supported by the feedback network configuration.

Part Context

This part belongs to the LT3976 family of synchronous step-down regulators. It shares the MSOP-16 footprint with other variants in the series but differs in electrical specifications such as current rating and quiescent current. It serves as a compact solution for converting higher bus voltages to lower logic or peripheral supply rails.
