LT8608SIV#TRMPBF

Overview

The LT8608SIV#TRMPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and delivers up to 1.5 A of continuous output current. The device features adjustable output voltage and utilizes peak current mode topology for fast transient response. Key electrical parameters include a quiescent current of 2.5 µA, a switch frequency range of 200 kHz to 2.2 MHz, and operation within a temperature range of -40°C to +125°C. It is housed in an LQFN-18 package.

Feature Summary

• Burst Mode operation enables high efficiency at very low output currents while maintaining low output ripple.
• Internal compensation allows the use of small inductors for compact designs.
• Integrated power good flag signals when the output voltage is within specified tolerances.

Applications

• Industrial control systems
• Point-of-load regulation
• Battery-powered equipment

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure compatibility with required operating temperatures and input voltage ranges before integration. Cross-reference datasheet revisions to confirm feature consistency.

Selection Notes

Select this component for applications requiring wide input voltage tolerance and high efficiency at light loads. Consider the LQFN-18 package size for space-constrained layouts. Evaluate thermal performance requirements given the 1.5 A output capability and available heat dissipation paths on the PCB.

Part Context

This part belongs to the LT8608 family of synchronous buck regulators designed for high efficiency and compact footprint. It shares architectural similarities with other members of the series but differs in package type and specific pin assignments. The SIV suffix indicates a specific surface-mount variant intended for automated assembly processes.
