LT8618EDDB#TRMPBF

Overview

The LT8618EDDB#TRMPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4V to 60V and provides a single adjustable output from 778mV to 25V at up to 100mA. The device features a low quiescent current of 1.7µA and supports switching frequencies between 200kHz and 2.2MHz. It is housed in a compact 10-WFDFN package with an exposed pad, suitable for surface mount installation across temperatures from -40°C to +125°C.

Feature Summary

• Synchronous buck topology for high efficiency
• Wide 60V input voltage capability
• Low quiescent current operation
• Adjustable switching frequency

Applications

• Industrial control systems
• Automotive electronics
• Distributed power architectures

Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape and reel packaging details. Ensure compatibility with the required operating temperature range and pinout configuration before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity.

Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside low standby power consumption. The adjustable output voltage and flexible switching frequency allow optimization for specific efficiency and EMI targets. Consider the 100mA output current limit and DFN-10 thermal performance for the intended load and enclosure constraints.

Part Context
