Overview
The LT1614IMS8#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 is housed in an 8-lead MSOP package and is rated for operation within a temperature range of -40°C to +85°C.
Feature Summary
- Implements Cuk topology to provide inverted negative output voltages from positive input sources
- Integrates a high-efficiency power switch capable of delivering up to 750mA
- Features a fixed internal oscillator operating at 600kHz for stable regulation
Applications
- Negative voltage generation for analog signal processing circuits
- Power supply stages requiring isolated negative rails from single positive inputs
- Battery-powered systems needing efficient step-up and inversion capabilities
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the IMS8 designation corresponds to the MSOP-8 package variant required for your PCB layout. Ensure compatibility with the 1V to 6V input range and negative output requirements before finalizing procurement specifications.
Selection Notes
Select this component when a negative output voltage is required from a low-voltage positive source. The Cuk topology allows for continuous input and output currents, which may reduce input filtering requirements compared to other topologies. Verify that the 750mA switch current rating meets the load demands and that the 600kHz frequency aligns with EMI constraints.
Part Context
This part belongs to the LT1614 family of switching regulators designed for low-voltage applications. It shares the core Cuk controller architecture with other variants but differs in package type and reel configuration. The IMS8 suffix specifically denotes the MSOP-8 plastic small outline package suitable for surface-mount assembly.
Replacement Considerations
Direct replacements include the LT1614IS8#PBF for tube packaging or the LT1614CS8#PBF for commercial grade. Verify pinout compatibility and thermal performance when substituting between different package styles or temperature grades.
