Overview
The LT1614CMS8#TRPBF is a Cuk switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range of 1V to 6V and provides an adjustable negative output voltage from -1.24V to -24V. The device supports a maximum switch current of 750mA and functions at a fixed switching frequency of 600kHz. It utilizes synchronous rectification and is housed in an 8-MSOP package suitable for surface mount applications.
Feature Summary
- Implements Cuk topology to generate stable negative output voltages from positive input sources
- Features integrated 750mA power switch for efficient energy transfer
- Supports wide input voltage range starting from 1V for low-voltage operation
Applications
- Portable battery-powered equipment requiring negative supply rails
- Industrial control systems utilizing single-supply architectures
- Communication interfaces needing dual polarity power distribution
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the MSOP-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system environment specifications before finalizing procurement.
Selection Notes
Select this component when a compact solution for generating negative voltage from a low-voltage source is required. The Cuk topology offers continuous input and output currents, reducing filtering requirements compared to other topologies. Consider the 600kHz frequency for balancing efficiency and external component size.
Part Context
This part belongs to the LT1614 family of switching regulators designed for high-efficiency DC-DC conversion. The CMS8 designation specifies the commercial temperature grade and MSOP-8 package variant. The #TRPBF suffix denotes the specific reel packaging configuration compliant with RoHS standards.
Replacement Considerations
LT1614CMS8#PBF is the tube-packaged equivalent of this component. Verify that the packaging difference does not impact your automated assembly process requirements.
