LT8640EUDC-1#TRPBF

Overview

The LT8640EUDC-1#TRPBF is a synchronous step-down switching regulator from the Silent Switcher family, manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4 V to 42 V and delivers up to 5 A of output current. The device features adjustable output voltages between 970 mV and 41.58 V, with a programmable switching frequency spanning 200 kHz to 3 MHz. Quiescent current is specified at 1.7 uA during operation. It utilizes a QFN-18 package and supports temperatures from -40 C to +125 C.

Feature Summary

Integrates Silent Switcher technology for minimized electromagnetic interference emissions without external shielding requirements.
Provides high-efficiency synchronous buck regulation with integrated power MOSFETs for compact design.
Features low quiescent current consumption to extend battery life in portable applications.

Applications

Automotive always-on systems
Industrial point-of-load regulation
Battery-powered digital devices

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the EUDC grade corresponds to the required operating temperature range for your application. Ensure compatibility with the DC2202A evaluation board if prototyping. Check manufacturer documentation for latest RoHS compliance status before finalizing procurement.

Selection Notes

Select this component for designs requiring wide input voltage ranges up to 42 V and high current capabilities. The Silent Switcher architecture is suitable for noise-sensitive environments. Consider the QFN-18 package constraints for thermal management. Verify that the 200 kHz to 3 MHz frequency range meets system timing requirements.

Part Context

This part belongs to the LT8640 series of Silent Switcher regulators. It shares core topology with variants like LT8640EUDC-1#PBF but differs in packaging format. The series is designed for automotive and industrial applications requiring high efficiency and low EMI performance.
