Overview
The LT1614IS8#PBF is a Cuk switching regulator IC manufactured by Analog Devices Inc., housed in an 8-SOIC package. It operates with a fixed switching frequency of 600kHz and supports an input voltage range from 1V to 6V. The device provides a single negative adjustable output ranging from -1.24V to -24V, delivering up to 750mA of switch current. It functions as a boost or buck-boost converter within the specified parameters.
Feature Summary
- Implements Cuk topology for efficient negative voltage generation
- Integrates a 600kHz fixed-frequency oscillator for consistent regulation
- Supports wide input voltage ranges suitable for low-voltage applications
Applications
- Portable battery-powered equipment requiring negative rails
- Industrial control systems needing isolated negative supplies
- Telecommunications infrastructure utilizing Cuk converter topologies
Procurement Notes
Verify the specific suffix IS8 against the required operating temperature range and package dimensions before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a negative output voltage is required from a low-voltage source. The Cuk topology offers continuous input and output currents, reducing filtering requirements compared to other topologies. Consider the 750mA switch current limit and the 600kHz frequency when designing passive components for the application.
Part Context
This part belongs to the LT1614 family of switching regulators designed for high-efficiency power conversion. The IS8 designation indicates the industrial temperature grade (-40°C to 85°C) and the SOIC-8 surface-mount package. It serves as a specialized solution for generating negative voltages in compact designs.
Replacement Considerations
LT1614CS8#PBF: Same functional specifications but rated for commercial temperature range (0°C to 70°C). Verify thermal requirements before substituting.
