LT1614CS8#TRPBF

Overview

The LT1614CS8#TRPBF is a Cuk switching regulator IC manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 600kHz and provides a single adjustable negative output voltage ranging from -1.24V to -24V. The device supports an input voltage range of 1V to 6V and delivers a switch current capability of 750mA. It is housed in an 8-SOIC package (3.90mm width) 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
Features a fixed internal switching frequency for simplified external component selection
Supports boost, buck-boost, and inverting configurations within a single integrated circuit

Applications

Negative power supply generation for operational amplifier circuits
Inverting DC-DC conversion in portable battery-powered instrumentation
Power management for RS-232 interface transceivers requiring dual polarity supplies

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the CS8 variant meets the required commercial temperature specifications for your application environment. Ensure compatibility with the 8-SOIC footprint during PCB layout planning.

Selection Notes

Select this component when a compact solution for generating negative voltages from low-voltage inputs is required. Consider the 600kHz frequency trade-off between component size and efficiency. Evaluate the 750mA switch current limit against peak load requirements to ensure adequate headroom.

Part Context

This part belongs to the LT1614 family of monolithic switching regulators designed for high-efficiency power inversion. It integrates the control logic and power switch into a small surface-mount package, reducing the bill of materials compared to discrete solutions.
