LT3492EFE#TRPBF

LED Driver IC Overview

The LT3492EFE#TRPBF 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 an input voltage range of 3V to 30V. Each channel features internal switches rated at 60V and supports up to 600mA output current. The switching frequency is adjustable between 330kHz and 2.1MHz. It provides 3000:1 PWM dimming ratio via an external input and includes a CTRL pin for analog dimming or overtemperature protection.

LED Driver IC Feature Summary

• True Color PWM Dimming delivers high contrast ratios
• Built-in gate driver for PMOS LED disconnect
• Three independent driver channels with integrated switches
• Open LED protection functionality

LED Driver IC Applications

• High current LED lighting systems
• LED backlighting applications
• General LED illumination circuits

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the component matches the 28-TSSOP-EP package specification. Check datasheet revisions for any parameter updates prior to final design integration.

LED Driver IC Selection Notes

Select this component for designs requiring three independent LED channels from a single controller. It is suitable for applications needing wide input voltage flexibility and precise current regulation. Consider the adjustable frequency range to optimize efficiency and passive component size. Verify that the required dimming range exceeds standard capabilities.

LED Driver IC Part Context

This part belongs to the LT3492 series of triple output LED drivers. It shares architectural similarities with other Linear Technology power management ICs but is specialized for multi-channel LED control. The device integrates power switches and control logic to simplify board layout compared to discrete solutions.

LED Driver IC Replacement Considerations

LT3492IUFD#TRPBF offers identical electrical specifications but utilizes a QFN-28 package instead of TSSOP. Verify footprint compatibility if substituting physically. No other direct functional substitutes are documented in the provided data.
