LT3003EMSE#PBF

LED Driver IC Overview

The LT3003EMSE#PBF is a triple-channel LED ballast controller manufactured by Analog Devices Inc., housed in a 10-pin MSOP MSE package. It supports input voltages up to 40V and delivers output currents ranging from 100mA to 350mA per channel. The device integrates non-ground referenced PWM dimming with capabilities reaching 3000:1 at 100Hz, eliminating the need for discrete MOSFETs. It operates in both buck and buck-boost topologies while maintaining logic-level PWM input requirements.

LED Driver IC Feature Summary

• Integrates three independent LED current channels within a single compact package
• Supports internal level-shifted PWM dimming without external discrete components
• Operates effectively in both buck and buck-boost voltage topologies

LED Driver IC Applications

• Multi-channel LED lighting systems requiring precise current regulation
• Applications utilizing non-ground referenced PWM dimming signals
• Compact LED drivers where discrete MOSFET elimination is required

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package integrity upon receipt, as the MSE variant requires specific thermal management considerations during assembly. Ensure that ordering suffixes match the exact pinout and thermal pad specifications documented in the official datasheet to prevent integration errors.

LED Driver IC Selection Notes

Select this component when designing circuits requiring simultaneous control of multiple LED strings with high dimming ratios. It is suitable for designs where space constraints prohibit external level-shifting transistors. Consider the thermal performance of the MSE package relative to the total power dissipation across all three channels during operation.
