Overview
The LT8608BIDC#TRMPBF is a synchronous step-down switching regulator from Analog Devices, housed in an 8-pin WDFN package with an exposed pad. It operates with an input voltage range of 3V to 42V and delivers a continuous output current of 1.5A. The device features adjustable output voltage starting from 0.778V and supports switching frequencies between 200kHz and 2.2MHz. Quiescent current consumption is specified at 1.7µA or 2.5µA depending on the operational mode. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Synchronous monolithic buck topology for high efficiency
- Ultra-low quiescent current operation
- Adjustable switching frequency up to 2.2MHz
- Wide input voltage capability
Applications
- Industrial distributed power systems
- Battery-powered equipment
- Embedded control applications
Procurement Notes
Verify the specific suffix TRMPBF against official Analog Devices documentation to confirm tape and reel packaging and lead-free status. Ensure the order matches the exact part number variant required for thermal and electrical specifications. Cross-reference the datasheet revision date to confirm compatibility with design requirements before finalizing procurement.
Selection Notes
Select this component when a wide input voltage range up to 42V is required alongside compact size constraints. The adjustable frequency allows optimization for EMI or component size trade-offs. Verify that the 1.5A continuous current rating meets load demands and that the 8-pin WDFN package fits the available PCB footprint.
Part Context
This part belongs to the LT8608 family of high-voltage buck regulators designed for space-constrained applications. It integrates the switch and controller into a single DFN package, reducing external component count compared to discrete solutions while maintaining performance suitable for industrial environments.
Replacement Considerations
Consult official Analog Devices substitution guides for verified equivalents. Generic replacements may not match the 42V input rating or specific thermal characteristics of the WDFN-8 package.
