Overview
The LT3489EMS8E#TRPBF is a DC-DC switching regulator manufactured by Analog Devices Inc., housed in an MSOP-8 package. It operates as a boost converter with an input voltage range of 3.3 V to 6 V. The device provides three regulated outputs: 8 V at 600 mA, -8 V at 20 mA, and 23 V at 10 mA. It achieves an efficiency of 83% and includes shutdown functionality.
Feature Summary
- Generates multiple output voltages including positive and negative rails from a single low-voltage input source
- Designed for driving TFT LCD displays with optimized component count and small footprint
- Integrates high-efficiency boost topology for power conversion applications
Applications
- TFT LCD display bias power supplies
- Multi-rail power generation from single-cell or dual-cell battery sources
- Portable electronic devices requiring compact DC-DC conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact MSOP-8 variant. Check current availability status as supply may be limited. Validate RoHS compliance requirements against project specifications before finalizing procurement.
Selection Notes
Select this component when a single-input, multi-output boost solution is required for LCD biasing. It is suitable for systems needing simultaneous positive and negative voltage rails. Consider the 600 mA capability on the primary rail for load requirements. Evaluate the MSOP-8 package size constraints against PCB layout limitations. Compare efficiency metrics against alternative converters for thermal management needs.
Part Context
This part belongs to the LT3489 family of high-efficiency DC-DC converters. It is specifically engineered for portable applications requiring multiple supply rails. The device integrates power switches and control circuitry into a compact form factor. It serves as a specialized solution for display driver power management in mobile electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing design-in alternatives through detailed electrical parameter comparison if substitution is necessary.
