Overview
The LT8331IMSE#TRPBF is a current mode DC/DC converter from Analog Devices, featuring an integrated 0.5A switch rated for 140V. It operates with an input voltage range of 4.5V to 100V and supports boost, SEPIC, flyback, and inverting topologies via a single feedback pin. The device offers a programmable switching frequency between 100kHz and 500kHz and maintains a low quiescent current of 5.5µA. It provides adjustable output voltages ranging from 1.6V to 140V or -0.8V to negative values, housed in a 16-MSOP-EP package.
Feature Summary
- Supports multiple converter configurations including boost, SEPIC, flyback, and inverting using a unique single feedback pin architecture
- Features ultra-low quiescent current consumption to maximize efficiency in battery-powered applications
- Includes internal compensation and soft-start circuitry for stable operation across wide input and output voltage ranges
- Utilizes Burst Mode operation to minimize output ripple while maintaining high efficiency at light loads
Applications
- Industrial control systems requiring isolated or non-isolated power conversion
- Automotive electronics operating within wide input voltage variations
- Medical diagnostic equipment needing low-noise power supplies
- Telecommunications infrastructure utilizing high-voltage input sources
Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm that the IMSE variant meets industrial temperature requirements (-40°C to +125°C). Ensure compatibility with the 16-MSOP-EP footprint during PCB layout. Check for AEC-Q100 qualification if automotive reliability standards are mandatory for the final assembly.
Selection Notes
Select this component when high input voltages up to 100V are required alongside flexible topology options. The internal 0.5A switch suits moderate power applications without external MOSFETs. Consider the programmable frequency range for optimizing inductor size versus EMI performance. Verify that the single feedback pin simplifies design compared to multi-pin regulator alternatives.
Part Context
This part belongs to the LT833x family of converters designed for versatile power management. Unlike fixed-function regulators, the LT8331 allows designers to implement various topologies using minimal external components. The series emphasizes low standby current and compact packaging solutions for space-constrained electronic designs.
Replacement Considerations
LT8331EMSE#TRPBF serves as a commercial grade alternative with identical electrical specifications but potentially different temperature ratings. LT8331IMSE#PBF offers the same functionality in tube packaging instead of tape-and-reel. Verify package dimensions and thermal characteristics before substituting.
