LT3596IUHG#PBF

LED Driver IC Overview

The LT3596IUHG#PBF is a 60V step-down LED driver IC from Analog Devices Inc. It features three independent output channels, each capable of delivering up to 100mA. The device operates with a switching frequency range of 200kHz to 1MHz and supports PWM dimming. It utilizes digital PWM dimming at 100Hz to achieve a contrast ratio of 10,000:1. The component is housed in a 52-QFN (5x8) package and is rated for an operating junction temperature range of -40°C to 125°C.

LED Driver IC Feature Summary

• Supports driving up to ten LEDs per channel using fast NPN current sources
• Provides high-contrast digital PWM dimming capability
• Integrates a synchronous buck topology for efficient voltage regulation

LED Driver IC Applications

• LED backlighting systems
• Signage illumination
• Indicator lighting circuits

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the 52-QFN package dimensions match the PCB footprint requirements. Ensure the input voltage supply does not exceed the 60V absolute maximum rating during operation.

LED Driver IC Selection Notes

Select this component for applications requiring multi-channel LED control with high dimming contrast. Consider the thermal performance of the QFN package for heat dissipation needs. Evaluate the 100mA per channel limit against total load requirements.
