Overview
The LT8618EDDB#WTRMPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4V to 60V and provides a single adjustable output from 778mV to 25V at up to 100mA. The device features a low quiescent current of 1.7µA and supports switching frequencies between 200kHz and 2.2MHz. It is housed in a compact 10-WFDFN package with exposed pad, suitable for surface mount installation across temperatures from -40°C to +125°C.
Feature Summary
- Synchronous buck topology designed for high efficiency in space-constrained applications
- Integrated 60V switch capability allows direct connection to industrial bus voltages
- Ultra-low quiescent current ensures minimal power consumption during standby modes
Applications
- Industrial point-of-load regulation
- Battery-powered equipment requiring extended runtime
- Embedded systems with wide input voltage ranges
Procurement Notes
Verify the specific suffix #WTRMPBF against official Analog Devices documentation to confirm tape and reel packaging specifications. Ensure compatibility with standard surface-mount reflow profiles. Cross-reference the exact part number with manufacturer datasheets to validate availability status and lead times prior to procurement planning.
Selection Notes
Select this component when designing circuits requiring a wide 60V input range and low standby current. The 100mA output current rating suits light-load applications. Consider the 10-WFDFN package size for board space optimization. Verify thermal requirements based on the specific duty cycle and ambient temperature conditions expected in the final assembly.
Part Context
This part belongs to the LT8618 family of synchronous buck converters. The series is characterized by its ability to handle high input voltages while maintaining small footprint dimensions. The EDDB variant specifically denotes the 10-lead DFN package configuration used for efficient heat dissipation and compact PCB layout integration within power management subsystems.
Replacement Considerations
Consult Analog Devices official substitution guides for verified alternatives. Generic replacements may differ in pinout or electrical characteristics.
