LT8606HDC#TRPBF

Overview

The LT8606HDC#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5 V to 42 V and delivers a maximum output current of 350 mA. The device features adjustable output voltage and supports switching frequencies between 200 kHz and 2.2 MHz. It exhibits a quiescent current of 2.5 µA and functions within a temperature range of -40 °C to +125 °C. The component is housed in an 8-pin HVSON package.

Feature Summary

• Integrates high-side and low-side N-channel power switches for efficient synchronous rectification
• Supports wide input voltage range up to 42 V for flexible power supply designs
• Offers programmable switching frequency from 200 kHz to 2.2 MHz to optimize external component size
• Maintains low quiescent current during operation to enhance efficiency under light loads

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Battery-powered equipment needing extended runtime through low standby current
• Embedded computing platforms utilizing adjustable voltage regulation
• Automotive electronics operating within specified thermal and voltage limits

Procurement Notes

Verify the exact suffix and tape-and-reel packaging configuration against official Analog Devices documentation before ordering. Confirm that the HVSON-8 footprint matches your PCB layout requirements. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any specific handling or storage instructions provided in the datasheet.

Selection Notes

Select this component when a compact solution is needed for inputs up to 42 V with moderate output current demands. Consider the trade-off between switching frequency and external inductor/capacitor sizes. Evaluate thermal performance based on the expected load and ambient conditions. Compare quiescent current specifications against other regulators in the same family if battery life is critical. Verify that the adjustable output range meets the target system voltage requirements.

Part Context

This part belongs to the LT8606 series of synchronous buck regulators from Analog Devices. It shares architectural similarities with other members like the LT8607 and LT8608, which offer higher current capabilities. The HDC suffix indicates the specific HVSON-8 package variant. This series is designed for applications requiring high efficiency and small form factors in power management circuits.

Replacement Considerations

LT8606EMSE#PBF offers the same electrical specifications but uses an MSOP-10 package instead of HVSON-8. LT8607 variants provide higher output current (750 mA) with similar input ranges. LT8608 variants support up to 1.5 A output current. Verify pin compatibility and thermal characteristics when substituting these parts.
