LED Driver IC datasheet and documents for LT3950EMSE#PBF

LT3950EMSE#PBF

LED Driver IC Overview

The LT3950EMSE#PBF is a multitopology DC/DC converter designed for high-current LED driving. It features an integrated 1.5A, 60V DMOS switch and supports boost, SEPIC, buck, and buck-boost modes. The device includes an internal PWM generator providing 128:1 exponential scale dimming and supports up to 20,000:1 external PWM dimming at 100Hz. It offers programmable switching frequencies from 300kHz to 2MHz, ±2% regulation accuracy for LED current and output voltage, and spread spectrum frequency modulation (SSFM) to reduce EMI.

LED Driver IC Feature Summary

Multitopology operation supporting boost, SEPIC, buck, and buck-boost configurations
Internal exponential scale PWM dimming with 128:1 resolution
Integrated 1.5A, 60V DMOS power switch
Spread spectrum frequency modulation for EMI reduction

LED Driver IC Applications

Display backlight illumination
Automotive lighting systems
Avionics lighting applications

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates leaded tape-and-reel packaging when sourcing. Confirm the operating temperature range matches the industrial grade designation if required for harsh environments. Ensure the input voltage supply remains within the 3V to 60V window during all transient conditions to prevent undervoltage lockout or overvoltage stress on the internal switch.

LED Driver IC Selection Notes

Select this component when a single IC must support multiple LED drive topologies to simplify board layout across different product variants. The integrated 1.5A switch eliminates the need for external power MOSFETs in moderate current applications. Choose this part if precise exponential dimming control is required without complex external microcontroller logic for dimming curve generation.

LED Driver IC Part Context

This device belongs to Analog Devices' family of high-voltage LED drivers. It shares architectural similarities with other LT39xx series parts but distinguishes itself through its ability to operate in both buck and boost modes within a single package. The 16-lead MSOP package provides a compact solution for space-constrained lighting designs requiring high efficiency and thermal performance.
