Overview
The LT8410EDC is a synchronous boost DC-to-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 16V and generates a regulated output voltage up to 16V. The device utilizes a fixed-frequency peak current mode control architecture, managing power delivery by varying both the peak inductor current and the switch off-time. It features an adjustable output voltage starting from 1.235V, with a maximum switch voltage rating of 40V. The component is housed in an 8-WFDFN package with exposed pad and supports operation across a temperature range of -40°C to 125°C TJ.
Feature Summary
- Synchronous rectification topology for improved efficiency
- Peak current mode control with variable peak inductor current and off-time
- Adjustable output voltage capability down to 1.235V
- Integrated high-side N-channel MOSFET switch
Applications
- Battery-powered systems requiring step-up conversion
- Industrial sensor interfaces
- Portable medical devices
- General-purpose isolated or non-isolated power supplies
Procurement Notes
Verify the specific suffix (e.g., #TRMPBF) against the required packaging format such as tape and reel or cut tape. Confirm the operating temperature grade matches the application environment. Ensure the 8-WFDFN footprint aligns with the PCB layout guidelines provided in the datasheet. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when an input voltage range of 2.5V to 16V is required with an output up to 16V. Consider the 6mA switch current limit for low-power applications. Evaluate the thermal performance within the 8-WFDFN package for the expected load conditions. Compare against non-synchronous alternatives if cost is a primary driver over efficiency.
Part Context
The LT8410 belongs to the LT8410 family of synchronous boost converters designed for space-constrained applications. It shares architectural similarities with other high-efficiency DC-DC regulators from Analog Devices but is distinct in its specific input/output voltage ranges and control methodology. The part is commonly paired with evaluation boards like the SCP-LT8410-EVALZ for design verification.
Replacement Considerations
LT8410EDC-1#TRMPBF is a verified variant within the same product line offering identical functionality with potential minor manufacturing lot differences.
