LT8607HDC#TRPBF

Overview

The LT8607HDC#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in an 8-lead DFN package. It operates with an input voltage range of 3 V to 42 V and delivers a continuous output current of 750 mA. The device features an adjustable output voltage and supports programmable switching frequencies between 200 kHz and 2.2 MHz. It draws a typical quiescent current of 1.7 µA when not switching and includes a shutdown pin for power management. The component functions within a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrated high-speed synchronous buck topology for efficient DC-to-DC conversion
• Ultra-low non-switching quiescent current consumption for extended battery life
• Programmable switching frequency allows optimization for size or efficiency
• Thermal performance rated for operation up to 150°C junction temperature

Applications

• Battery-powered portable equipment requiring low standby current
• Industrial systems operating from wide input voltage rails
• Embedded controllers needing compact synchronous step-down regulation
• Automotive electronics compatible with 12V or 24V nominal systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration. Confirm the H-grade thermal rating matches application requirements against standard variants. Ensure the DFN-8 footprint aligns with PCB layout constraints. Cross-reference the manufacturer datasheet for RoHS compliance details and handling precautions relevant to the exposed pad design.

Selection Notes

Select this variant over MSOP packages when board space is limited due to the smaller DFN-8 footprint. Choose based on the requirement for a shutdown control pin, which distinguishes it from non-shutdown versions. Consider the 1.7 µA quiescent current specification for applications prioritizing energy conservation during idle states compared to higher current alternatives.

Part Context

This component belongs to the LT8607 family of high-efficiency synchronous regulators. It shares core electrical specifications with other package options like the MSOP version but differs in physical dimensions and thermal characteristics. The series is designed for applications demanding high power density and wide input voltage tolerance in a minimal form factor.

Replacement Considerations

LT8607HMSE#TRPBF offers identical electrical performance in a larger MSOP-10 package without a shutdown pin.
