LT3755EUD-1#PBF

LED Driver IC Overview

The LT3755EUD-1#PBF is a DC/DC controller designed as a constant-current source for driving high-current LEDs. It features an internal regulated 7.15V supply to drive external low-side N-channel power MOSFETs. The device utilizes a fixed-frequency, current-mode architecture for stable operation across wide input and output voltage ranges. Key electrical parameters include a maximum input voltage of 40V, a maximum output voltage of 75V, and a switching frequency range of 100kHz to 1MHz. It supports analog and PWM dimming methods.

LED Driver IC Feature Summary

Fixed-frequency current-mode architecture ensures stable operation over wide supply and output voltage variations
Internal regulated 7.15V supply drives external low-side N-channel power MOSFETs
Supports both analog and pulse-width modulation (PWM) dimming techniques

LED Driver IC Applications

High-current LED lighting systems requiring constant-current regulation
Automotive exterior lighting applications utilizing PWM dimming
Industrial LED drivers operating within specified voltage limits

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tape-and-reel or tube packaging as per manufacturer standards. Confirm the 16-WFQFN package type matches your PCB footprint requirements. Ensure the 40V input and 75V output ratings align with your system design constraints before procurement.

LED Driver IC Selection Notes

Select this component when a single-output, high-voltage LED driver is required with integrated control logic. The fixed-frequency operation simplifies EMI filter design compared to variable-frequency alternatives. Consider the external MOSFET requirement for power handling versus integrated solutions if space is limited.

LED Driver IC Part Context

This part belongs to the LT3755 family of LED controllers from Analog Devices. It is specifically configured for single-output applications, distinguishing it from multi-channel variants in the same series. The device integrates control circuitry while relying on external power components for current delivery.
