Overview
The LT1680CSW#PBF is a high-power DC/DC step-up controller optimized for boost and forward converter topologies. It operates within an input voltage range of 4V to 60V, supporting adjustable output voltages. The device features a switching frequency of 200 kHz and delivers up to 700 mA output current. Designed for surface-mount applications in SO-16 packages, it functions across temperatures from 0°C to +70°C with a quiescent current of 150 µA.
Feature Summary
- Optimized for high-power boost and forward converter topologies
- Supports wide input voltage range from 4V to 60V
- Integrated shutdown capability for power management
Applications
- Industrial power supply systems
- Battery-powered equipment requiring step-up conversion
- Telecommunications infrastructure power modules
Procurement Notes
Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm package integrity and pin alignment against the SO-16 specification. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference datasheet revisions to confirm compatibility with existing design parameters.
Selection Notes
Select this controller for designs requiring robust boost conversion with wide input tolerance. Consider thermal dissipation capabilities given the 700 mA output rating. Evaluate PCB layout constraints for the SO-16 surface mount package. Verify that the 200 kHz switching frequency aligns with electromagnetic interference limits and filter component selections.
Part Context
Part of the LT1680 series, which includes variants like LT1680CN#PBF offering through-hole options. The CSW suffix denotes the specific SO-16 surface mount package configuration. This series targets applications demanding high efficiency and reliable performance in industrial environments.
Replacement Considerations
LT1680CN#PBF serves as a direct functional alternative with identical electrical specifications but utilizes a PDIP-16 through-hole package instead of the SO-16 surface mount format.
