LT3492IFE#PBF

LED Driver IC Overview

The LT3492IFE#PBF is a triple output DC/DC converter designed as a constant-current source for driving LEDs. It operates in buck, boost, or buck-boost modes with internal switches rated at 60V and 600mA per channel. The device supports an input voltage range of 3V to 30V and features adjustable switching frequencies between 330kHz and 2.1MHz. It provides up to 3000:1 PWM dimming ratio via True Color PWM technology and includes built-in gate drivers for external PMOS LED disconnect. The CTRL pin allows for analog dimming or overtemperature protection.

LED Driver IC Feature Summary

• Triple independent driver channels with integrated 60V, 600mA switches
• Supports buck, boost, and buck-boost topologies for flexible LED configurations
• True Color PWM delivers high-range dimming without color shift
• Built-in gate drivers enable external PMOS LED disconnect control

LED Driver IC Applications

• High current LED lighting systems
• Automotive interior and exterior illumination
• General solid-state lighting applications requiring multiple channels

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the IFE package variant matches the required thermal and footprint specifications for the target PCB design. Ensure supply chain sources are authorized to guarantee component authenticity and traceability.

LED Driver IC Selection Notes

Select this component when three independent LED channels are required within a single IC solution. It is suitable for designs needing wide input voltage flexibility and precise current regulation. Consider the thermal performance of the TSSOP-EP package relative to the total power dissipation of all three channels under maximum load conditions.

LED Driver IC Part Context

This part belongs to the LT3492 family of triple output LED drivers from Analog Devices. It shares architectural similarities with other Linear Technology LED controllers but is distinct in its specific switch ratings and package configuration. The device integrates control logic and power stages to simplify multi-channel LED driver board layouts.

LED Driver IC Replacement Considerations

LT3492EFE#TRPBF offers identical electrical functionality but utilizes a TSSOP-28 package instead of QFN-28. Verify package compatibility and thermal management requirements when substituting. No other direct functional equivalents are documented in the provided data.
