Overview
The LT8608BEDC#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and delivers a continuous output current of 1.5 A. The device features adjustable output voltage and supports switching frequencies between 200 kHz and 2.2 MHz. Quiescent current consumption is specified at 2.5 uA. It utilizes a DFN-8 surface-mount package and functions within a junction temperature range of -40 C to +125 C.
Feature Summary
- Synchronous buck topology for high efficiency
- Low quiescent current operation
- Adjustable output voltage capability
Applications
- General purpose power management
- Industrial control systems
- Distributed power architectures
Procurement Notes
Verify the specific suffix BEDC against official datasheets to confirm pinout and thermal pad configuration. Confirm RoHS compliance status through manufacturer documentation. Ensure the DFN-8 package dimensions match PCB footprint requirements. Validate operating temperature ranges against system environmental constraints before finalizing procurement.
Selection Notes
Select this component when a compact solution is required for 42V input systems. The low quiescent current supports battery-powered applications requiring extended standby life. The wide switching frequency range allows optimization for size versus efficiency trade-offs. Verify that the 1.5A output current meets load requirements under all thermal conditions.
Part Context
This part belongs to the LT8608 series of synchronous step-down regulators from Analog Devices. The series is designed for applications demanding high efficiency in small form factors. The BEDC suffix indicates a specific package variant within the broader LT8608 product family, sharing core electrical characteristics with other LT8608 models.
Replacement Considerations
LT8608EMSE#PBF shares similar electrical specifications but uses an MSOP-10 package. LT8608HMSE#PBF offers comparable performance in a different package style. Verify pin compatibility and thermal dissipation capabilities when substituting these variants.
