LT1184CS#TRPBF

Special Purpose Regulators Overview

The LT1184CS#TRPBF is a CCFL switching regulator IC in a 16-pin SOIC package. It operates with an input voltage range of 3V to 30V and features a switching frequency of 200kHz. The device includes a high-current switch capable of delivering 1.25A for CCFL applications. It supports grounded lamp configurations and incorporates open-lamp protection circuitry.

Special Purpose Regulators Feature Summary

• Integrates high-efficiency switches and control logic for cold cathode fluorescent lighting
• Includes built-in oscillator, reference, and comprehensive protection circuitry
• Supports grounded lamp configurations with open-lamp detection

Special Purpose Regulators Applications

• Notebook and Palmtop Computers
• Portable Instruments
• Automotive Displays
• Retail Terminals

Special Purpose Regulators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the component is manufactured by Analog Devices Inc. or its predecessor Linear Technology. Ensure the datasheet matches the LT1184 specification for CCFL regulation. Check for any environmental compliance markings relevant to the manufacturing date code.

Special Purpose Regulators Selection Notes

Select this component specifically for grounded lamp CCFL backlighting applications. It is suitable for designs requiring a wide input voltage range up to 30V. The integrated 1.25A switch current capability supports standard CCFL loads. Consider the 16-SOIC package size for PCB layout constraints.

Special Purpose Regulators Part Context

This part belongs to the LT1182/LT1183/LT1184 family of CCFL and LCD contrast switching regulators. Unlike the LT1182 and LT1183, the LT1184 does not support LCD contrast functions. It differs from the LT1184F by supporting only grounded lamp configurations rather than floating ones.

Special Purpose Regulators Replacement Considerations

LT1184FCS#TRPBF supports both grounded and floating lamp configurations, offering greater flexibility than the LT1184CS#TRPBF which is limited to grounded lamps.
