LT8619EDD#TRPBF

Overview

The LT8619EDD#TRPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 60V and delivers up to 1.2A of output current. The device features a fixed switching frequency of 1.5MHz and supports adjustable frequencies from 300kHz to 2.2MHz. It includes a low quiescent current mode of 6µA, integrated bootstrap diode, and thermal regulation. The component is housed in a thermally enhanced 16-lead MSOP package.

Feature Summary

• Integrated high-side bootstrap diode eliminates external components
• Thermal regulation limits junction temperature without cycle skipping
• Low noise burst mode operation for high efficiency at light loads

Applications

• Industrial point-of-load regulation
• Automotive infotainment systems
• Telecommunications equipment power distribution

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure compatibility with your PCB layout requirements regarding the exposed pad thermal connection. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a wide input voltage range up to 60V is required in a compact surface-mount package. It is suitable for applications needing high efficiency under varying load conditions. Consider the 1.5MHz fixed frequency option if minimizing external passive component size is a priority over variable frequency flexibility.

Part Context

This part belongs to the LT8619 family of micropower synchronous buck regulators. It shares architectural similarities with other high-voltage converters in the series but offers specific integration benefits like the internal bootstrap diode. The EDD suffix denotes the specific 16-lead MSOP package variant designed for improved thermal performance.
