Overview
The LT8608HDC#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in an 8-lead DFN package. It supports an input voltage range of 3V to 42V and delivers a continuous output current of 1.5A with adjustable output voltage. The device features a low quiescent current of 1.7µA and operates at switch frequencies between 200kHz and 2.2MHz. It functions within a temperature range of -40°C to +125°C junction temperature.
Feature Summary
- High efficiency Burst Mode operation maintains low output ripple below 10mV at very low load currents.
- Internal compensation with peak current mode topology enables the use of small inductors for fast transient response.
- Integrated power good flag signals when output voltage is within tolerance or indicates fault conditions.
Applications
- Industrial equipment power distribution
- Point-of-load regulation for embedded systems
- Battery-powered instrumentation
Procurement Notes
Verify the specific suffix against official documentation to confirm thermal grade and packaging details. Ensure compatibility with required operating temperatures and input voltage ranges. Confirm availability status through authorized channels as supply may be restricted.
Selection Notes
Select this component for designs requiring wide input voltage coverage up to 42V in a compact footprint. Consider the internal compensation for simplified layout requirements. Evaluate the 1.5A current limit against peak load demands to ensure stable operation under all conditions.
Part Context
This part belongs to the LT8608 family of high-speed synchronous buck regulators. It shares core architecture with variants like LT8608EDC and LT8608BEDC, differing primarily in thermal performance grades and package configurations. The series is designed for applications demanding high efficiency and small solution size.
Replacement Considerations
LT8608EDC#TRMPBF and LT8608BEDC#TRPBF are related parts within the same family. Verify if the specific thermal rating or package variant meets the design requirements before substitution.
