LTC7860HMSE#TRPBF

Overview

The LTC7860HMSE#TRPBF is a synchronous step-down DC/DC controller designed for high-voltage applications, supporting input voltages up to 150V. It features low quiescent current operation and integrates a fast protected high-side NMOS static switch driver. The device supports adjustable switching frequencies and includes comprehensive protection features such as overvoltage, undervoltage, and thermal shutdown. Packaged in a 16-lead MSOP package, it is suitable for industrial and automotive environments requiring efficient power conversion from high-voltage sources.

Feature Summary

• Integrates a fast protected high-side NMOS static switch driver for simplified implementation
• Supports synchronous step-down topology with low quiescent current for improved efficiency
• Includes built-in protection mechanisms against overvoltage, undervoltage, and thermal events

Applications

• Industrial motor drives and control systems
• Automotive electronics and battery management systems
• High-voltage point-of-load regulation

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's official documentation before procurement. Ensure that the requested part matches the exact electrical specifications and pinout requirements of the target design. Confirm availability status through authorized distributors, as supply constraints may apply to certain manufacturing batches or regions.

Selection Notes

Select this component when designing systems requiring direct drive of high-side NMOS transistors from high-voltage inputs without external bootstrap circuits. Consider the operating temperature range and package thermal characteristics for high-power applications. Validate compatibility with external passive components and switching frequency settings to meet system efficiency and size constraints.

Part Context

This part belongs to the LTC7860 family of high-voltage synchronous buck controllers from Analog Devices. It is distinct from lower voltage regulators and surge protectors within the broader LT series portfolio. The HMSE variant specifies the commercial temperature grade and MSOP packaging, differentiating it from other thermal or package options available in the same functional family.
