LT8672EMS#WPBF

Overview

The LT8672EMS#WPBF is a synchronous step-down DC/DC converter from Analog Devices, designed for high-efficiency power conversion in compact spaces. It integrates high-side and low-side N-channel MOSFETs to minimize external component count. The device supports an input voltage range of 3.5V to 42V and delivers up to 6A of output current. Key features include Silent Switcher technology for reduced electromagnetic interference (EMI) and a fixed switching frequency of 500kHz. It operates within a temperature range of -40°C to +125°C and utilizes an MSOP-10 package.

Feature Summary

• Integrates high-side and low-side N-channel MOSFETs for simplified design
• Silent Switcher architecture minimizes radiated EMI without external snubbers
• Fixed 500kHz switching frequency optimizes size and performance
• Supports wide input voltage range from 3.5V to 42V

Applications

• Industrial point-of-load regulation
• Automotive infotainment systems
• Telecommunications equipment
• Computing and networking infrastructure

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents. Cross-reference with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a compact solution with integrated power switches is required. Ensure the input voltage does not exceed 42V and the load current remains within the 6A limit. Consider thermal management requirements due to the dense integration of MOSFETs in the MSOP-10 package. Verify that the 500kHz frequency aligns with system noise constraints.

Part Context

The LT8672 belongs to Analog Devices' Silent Switcher family, which focuses on reducing EMI in buck converters. This series is engineered for applications where space is limited and electromagnetic compatibility is critical. The EMS variant specifically denotes the MSOP-10 package option, distinguishing it from other pinout configurations within the same functional family.

Replacement Considerations

Direct replacements may include other Silent Switcher buck converters from Analog Devices such as the LT8610 or LT8643 series, depending on specific voltage and current requirements. Verify pin compatibility and thermal characteristics when substituting.
