Overview
The LT8331EMSE#TRPBF is a current mode DC/DC converter from Analog Devices Inc., operating with an input voltage range of 4.5V to 100V. It features a robust internal switch capable of handling up to 140V and delivering a maximum output current of 500mA. The device supports adjustable output voltages, ranging from 1.6V for boost configurations to -0.8V for inverting topologies. It operates at a switching frequency between 100kHz and 500kHz and includes a shutdown function. Designed for surface mount installation, it utilizes a 16-MSOP package with an exposed pad (12 leads) and functions within a junction temperature range of -40°C to 125°C.
Feature Summary
- Supports multiple topologies including boost, SEPIC, flyback, and inverting configurations via a unique single feedback pin architecture.
- Features low quiescent current operation with a typical working supply current of 5.5uA and shutdown capability.
- Integrates a high-voltage 140V switch rated for 0.5A continuous current.
- Operates over a wide input voltage range from 4.5V to 100V.
Applications
- Automotive power systems requiring high input voltage tolerance
- Medical equipment power supplies
- Industrial control systems
- Battery-powered devices needing efficient step-up or inversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the component meets RoHS compliance standards as listed in the manufacturer's documentation. Ensure the design accounts for the thermal requirements of the MSOP-EP package. Cross-reference the datasheet for any recent product change notices regarding marking or material declarations before finalizing procurement.
Selection Notes
Select this component when a wide input voltage range up to 100V is required alongside flexible topology options. It is suitable for designs needing isolation or negative rail generation without external optocouplers in certain flyback applications. Consider the 500mA current limit and 140V switch rating for load requirements. The single feedback pin simplifies layout compared to multi-pin controllers.
Part Context
This part belongs to the LT8331 family of micropower switching regulators. It shares architectural similarities with other members like the LT8330 but offers higher voltage and current capabilities. The EMSE designation specifies the 16-lead MSOP package with an exposed pad, distinguishing it from smaller packages used in lower-power variants within the same series.
Replacement Considerations
LT8331EMSE#PBF is the tube-packaged equivalent of this component. Verify if the application requires tape-and-reel processing versus manual loading from tubes. No direct cross-brand replacements are confirmed in the provided data.
