LT8393EFE#PBF

LED Driver IC Overview

The LT8393EFE#PBF is a synchronous 4-switch buck-boost LED driver controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 60 V and supports output voltages up to 100 V. The device regulates LED current up to 300 mA and features a programmable switching frequency from 350 kHz to 2 MHz. It includes PWM dimming capabilities and open LED protection. The controller functions within a temperature range of -40°C to +125°C, utilizing a TSSOP-28-EP package for surface mount installation.

LED Driver IC Feature Summary

• Synchronous four-switch buck-boost topology enables regulation when input voltage is above, below, or equal to the output voltage.
• Integrated PWM dimming control allows for precise brightness adjustment of connected LED loads.
• Built-in open LED protection safeguards the circuit against fault conditions during operation.

LED Driver IC Applications

• LED lighting driver systems requiring wide input voltage ranges
• Industrial illumination applications with high output voltage requirements
• Automotive exterior lighting circuits

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the TSSOP-28-EP package variant matches the thermal pad requirements of the target PCB layout. Ensure the supplier provides valid traceability documentation for Analog Devices Inc. components to guarantee authenticity and performance consistency in critical LED driver designs.

LED Driver IC Selection Notes

Select this component when the application demands a single controller to handle both buck and boost operations across a wide voltage span. The 60 V input limit and 100 V output capability define the operational boundaries. Consider the TSSOP-28-EP package for its exposed pad thermal management advantages over standard QFN options in high-power density LED implementations.

LED Driver IC Part Context

This part belongs to the LT8393 series of synchronous buck-boost controllers designed specifically for LED applications. It differs from general-purpose regulators by optimizing for constant current LED drive characteristics. The EFE#PBF designation specifies the TSSOP-28-EP package and lead-free finish, distinguishing it from other pinout or thermal variants within the broader LT839x family.

LED Driver IC Replacement Considerations

LT8393EFE#TRPBF offers identical electrical specifications but utilizes a tape-and-reel packaging format instead of tube packaging. Verify that the reel quantity and handling procedures align with automated assembly requirements without altering the functional performance of the LED driver circuit.
