Overview
The LT3580EMS8E#TRPBF is a monolithic DC/DC converter manufactured by Analog Devices Inc., housed in an 8-lead MSOP package with an exposed thermal pad. It integrates a 2A switch capable of handling input voltages from 2.5V to 32V and switching frequencies between 200kHz and 2MHz. The device supports boost, Cuk, SEPIC, and inverting topologies, providing adjustable output voltages up to 42V. It features integrated soft-start functionality and operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple conversion topologies including boost, Cuk, SEPIC, and inverting configurations for flexible power design
- Integrates a high-current 2A internal switch for efficient power delivery in compact layouts
- Includes programmable soft-start capability to limit inrush current during startup
Applications
- Negative voltage generation for analog circuits
- Single-supply battery charging systems
- Driving N-channel power MOSFETs in high-side applications
Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm that the MSOP-EP package requires adequate thermal management on the PCB ground plane. Ensure the selected supplier provides valid traceability documentation for this Analog Devices component.
Selection Notes
Select this component when designing converters requiring both positive and negative outputs or single-supply operation. The wide input voltage range accommodates various battery chemistries. Consider the exposed pad for thermal dissipation if operating near maximum load currents.
Part Context
This part belongs to the LT3580 family of mixed-signal power management ICs. It is designed for applications needing versatile DC/DC conversion without external inductors in certain topologies. The MSOP-EP package allows for high-density board space utilization while maintaining thermal performance.
Replacement Considerations
LT3580EMS8E#PBF is the leaded equivalent variant. LT3580IDD offers the same functionality in a DFN package.
