LX1691AIPW

Lighting, Ballast Controllers Overview

The LX1691AIPW is an enhanced Direct Drive Cold Cathode Fluorescent Lamp (CCFL) controller manufactured by Microchip Technology. It operates within a supply voltage range of 2.8 V to 5.5 V, with a typical operating voltage of 3.3 V. The device is housed in a 16-pin TSSOP package and functions as a fluorescent light controller using pulse width modulation technology. It supports input voltages from single lithium-ion batteries and includes features such as active high output voltage regulation and a 120 ms power-on delay.

Lighting, Ballast Controllers Feature Summary

• Supports multiple dimming modes including amplitude and duty cycle control with digital or analog inputs
• Utilizes patented breakdown method via frequency scanning to generate appropriate ignition voltage without high-voltage spikes
• Integrates full-wave rectifier and stable oscillator to minimize external component requirements
• Provides fault protection mechanisms including open lamp voltage regulation and overvoltage/overcurrent shutdown

Lighting, Ballast Controllers Applications

• Notebook computer displays
• Portable electronic devices
• Digital cameras
• Personal Digital Assistants (PDAs)

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix IPW confirms the 16-pin TSSOP plastic package and RoHS compliance status. Confirm the manufacturer designation aligns with Microchip Technology following the acquisition of Microsemi. Ensure the datasheet version matches the required operational specifications for your circuit design.

Lighting, Ballast Controllers Selection Notes

Select this component for applications requiring direct drive CCFL backlighting with wide input voltage flexibility. It is suitable for designs powered by single-cell lithium-ion batteries. Consider the 16-pin TSSOP footprint for space-constrained portable electronics. Verify compatibility with existing PWM or analog dimming control signals before integration.

Lighting, Ballast Controllers Part Context

This part belongs to the LX1691 family of enhanced multi-mode CCFL controllers. It shares architectural similarities with the LX1691B but is distinguished by its specific packaging and electrical parameter tolerances defined by Microchip Technology. The series targets low-power display illumination solutions.

Lighting, Ballast Controllers Replacement Considerations

The LX1691BIPW is a related variant within the same product family. Verify pinout compatibility and specific electrical limits before substitution. Consult official documentation to confirm functional equivalence regarding dimming modes and fault protection thresholds.
