LT1614CMS8#PBF

Overview

The LT1614CMS8#PBF is a Cuk switching regulator IC manufactured by Analog Devices Inc., housed in an 8-MSOP package. It operates as a negative output DC-DC converter with adjustable voltage ranging from -1.24V to -24V. The device supports a maximum switch current of 750mA and functions at a fixed switching frequency of 600kHz. It accepts an input voltage between 1V and 6V, delivering a single regulated output. The component is rated for operation within a temperature range of 0°C to +70°C.

Feature Summary

• Implements Cuk topology for efficient negative voltage conversion
• Provides fully adjustable output voltage control
• Integrates a 750mA internal power switch
• Operates at a fixed 600kHz switching frequency

Applications

• Negative rail generation for mixed-signal circuits
• Power supply stages requiring isolated negative voltages
• Battery-powered systems needing step-up/step-down negative regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the MSOP-8 package dimensions match the target PCB footprint. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc. manufacturer part number.

Selection Notes

Select this component when a negative output voltage is required from a low-voltage source. The Cuk topology allows for continuous input and output currents, reducing filtering requirements. Verify that the input voltage range of 1V to 6V aligns with the system's available power rails.

Part Context

This part belongs to the LT1614 family of Cuk regulators. It is distinct from other Analog Devices switching regulators by its specific capability to generate negative outputs efficiently. The CMS8 designation specifies the commercial temperature grade and the MSOP surface-mount package type.
