Overview
The LT3684EMSE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts input voltages from 3.6V to 34V, with a maximum rating of 36V. The device provides a positive adjustable output voltage starting at 1.265V and delivers up to 2A of output current. Its switching frequency is adjustable between 300kHz and 2.8MHz. The component operates within a junction temperature range of -40°C to 125°C and is housed in a 10-MSOP package with an exposed pad.
Feature Summary
- Adjustable switching frequency allows optimization for size and efficiency across a wide range.
- Wide input voltage range supports operation from low supply levels up to 36V maximum.
- Integrated synchronous rectification ensures high efficiency during power conversion.
Applications
- Battery-powered portable equipment requiring efficient step-down regulation
- Industrial systems utilizing 24V or 48V bus architectures
- Embedded controllers needing isolated or non-isolated DC-DC conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check for RoHS compliance status as per the latest datasheet revision. Validate the 10-MSOP package type matches your PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when input voltages exceed standard LDO capabilities but remain below 36V. The adjustable frequency feature is critical for minimizing external inductor size in space-constrained designs. Ensure the required output current does not exceed 2A. Consider thermal performance due to the exposed pad requirement for heat dissipation in the MSOP package.
Part Context
This part belongs to the LT3684 family of high-efficiency buck regulators. It shares architectural similarities with the LT3680 and LT3685 but differs in output current ratings and specific pin configurations. The EMSE variant specifically denotes the MSOP package option within the broader LT3684 product line offered by Analog Devices.
Replacement Considerations
LT3684IMSE#TRPBF serves as a direct equivalent with identical electrical specifications and pinout compatibility. Verify that any substitute maintains the same 10-MSOP exposed pad footprint and thermal characteristics to ensure seamless integration without PCB redesign.
