Overview
The LT8620EMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4 V to 65 V and delivers up to 2 A of output current. The device features a fixed switching frequency of 2.2 MHz and supports adjustable output voltages from 970 mV to 64.75 V. It exhibits a quiescent current of 2.5 uA and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-lead MSOP package with an exposed pad.
Feature Summary
- Integrates top and bottom power switches to minimize external component requirements
- Supports wide input voltage ranges up to 65 V for flexible system design
- Features low quiescent current consumption for efficient standby operation
Applications
- Industrial equipment power distribution
- Automotive electronics systems
- Telecommunications infrastructure
- Point-of-load regulation modules
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm electrical characteristics, as variations exist within the LT8620 family. Confirm RoHS compliance status through manufacturer datasheets. Ensure compatibility with the intended thermal management solution given the MSOP-16 package constraints. Validate that the fixed 2.2 MHz switching frequency aligns with electromagnetic interference requirements for the target application environment.
Selection Notes
Select this part when a high-voltage input capability up to 65 V is required alongside a compact form factor. The fixed 2.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the -40°C to +125°C operating range for industrial or automotive environments. Verify that the 2 A continuous output current meets the load requirements without exceeding thermal limits in the chosen enclosure.
Part Context
This component belongs to the LT8620 series of synchronous buck regulators designed for high-efficiency power conversion. The EMSE variant specifically denotes the commercial temperature grade and MSOP-16 packaging. It shares architectural similarities with other members of the family but differs in temperature ratings and switching frequency configurations. The series targets applications requiring robust performance in space-constrained designs.
Replacement Considerations
LT8620HMSE#PBF offers extended temperature capabilities up to +150°C. LT8620MPMSE#PBF provides automotive-grade reliability with extended temperature ranges. Both variants maintain similar electrical parameters but differ in qualification standards and thermal specifications.
