LT8609SEV#TRPBF

Overview

The LT8609SEV#TRPBF is a dual-channel synchronous step-down Silent Switcher 2 regulator from Analog Devices. It provides up to 6A DC per channel, with peak capability of 8A on either channel. The device operates with an input voltage range of 3.0V to 42V and features adjustable switching frequencies between 300kHz and 3MHz. It incorporates internal bypass capacitors for ultralow EMI performance and offers Burst Mode operation with quiescent current as low as 6.2μA. The component is housed in a 4mm x 6mm 32-lead LQFN package with an exposed die.

Feature Summary

• Silent Switcher 2 architecture eliminates PCB layout sensitivity and reduces radiated EMI through integrated bypass capacitors.
• Dual-channel design delivers high efficiency at high frequencies with fast minimum switch-on time.
• Ultralow quiescent current in Burst Mode operation ensures minimal power consumption during light loads.

Applications

• Automotive supplies
• Industrial supplies
• General purpose step-down conversion

Procurement Notes

Verify the specific suffix 'SEV' against official Analog Devices documentation to confirm pinout and thermal characteristics. Ensure compatibility with the required 32-lead LQFN footprint. Confirm AEC-Q100 qualification status if automotive reliability is mandatory for the application.

Selection Notes

Select this component when dual isolated outputs are required within a compact form factor. The wide input voltage range supports various bus architectures. Consider the exposed die package for thermal management requirements associated with high continuous current loads.

Part Context

This part belongs to the LT8609 family of dual-channel regulators. It utilizes second-generation Silent Switcher technology to minimize electromagnetic interference without external snubbers. The family is designed for applications demanding high efficiency and low noise in space-constrained environments.

Replacement Considerations

LT8609SIV#PBF: Single channel variant with similar electrical specifications but different pin count and package type.
