CAT4106YP-T2

Overview

The CAT4106YP-T2 is a quad-channel DC/DC LED driver from onsemi, designed for backlighting applications up to 6W. It features an integrated boost converter with a 3V to 5.5V input range and 1MHz switching frequency. Each channel delivers constant current up to 175mA, supporting LED string voltages of 36V. The device uses a TSSOP-16 package and includes PWM dimming and open LED protection diagnostics.

Feature Summary

• Integrates a high-power DC-DC boost converter for efficient multi-channel LED driving
• Provides precise uniform drive current programming via a single external resistor
• Includes on-chip diagnostic functions such as open LED protection

Applications

• General LCD backlighting systems
• Multi-string LED illumination circuits
• High-efficiency LED driver designs

Procurement Notes

Verify the specific suffix 'YP' against the official datasheet to confirm pinout and thermal pad configuration. Check component lifecycle status as obsolescence may affect long-term availability. Ensure compatibility with existing PCB footprints and design specifications before procurement.

Selection Notes

Select this component for applications requiring four independent LED channels driven by a single boost topology. It is suitable for designs needing up to 175mA per channel with total power constraints around 6W. Consider the TSSOP-16 package for surface-mount assembly requirements.

Part Context

This part belongs to the CAT4106 series of quad-channel LED drivers. It shares functional similarities with the CAT4106HV4-GT2 but differs in packaging. The series targets general LCD backlighting with integrated diagnostics and boost conversion capabilities.

Replacement Considerations

The CAT4106HV4-GT2 is a documented alternative within the same product family. Verify package differences between TSSOP-16 and TQFN-16 layouts during substitution.
