LED Driver IC datasheet and documents for LT3942HUFD#PBF

LT3942HUFD#PBF

LED Driver IC Overview

The LT3942HUFD#PBF is a monolithic 4-switch synchronous buck-boost converter and LED driver manufactured by Analog Devices Inc. It features four independent channels with a maximum output current of 2A per channel. The device operates within an input voltage range of 3V to 60V and supports adjustable output voltages. Switching frequencies are programmable from 300kHz to 2MHz. It includes PWM dimming capabilities and open LED protection. The component is housed in a QFN-28 package and functions across temperatures from -40°C to +150°C.

LED Driver IC Feature Summary

Integrates a 4-switch synchronous buck-boost topology for versatile input-output voltage relationships
Provides four independent regulated channels for multi-string LED applications
Supports both analog and PWM dimming methods for brightness control
Includes built-in open LED protection mechanisms

LED Driver IC Applications

General purpose lighting systems
LED backlight drivers
Industrial illumination fixtures

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the QFN-28 package dimensions against your PCB footprint requirements. Ensure the design accommodates the thermal characteristics associated with the 2A per channel output capability. Cross-reference the manufacturer's latest datasheet for any updates regarding operating conditions or recommended circuit components.

LED Driver IC Selection Notes

Select this component when a single IC must handle both buck and boost operations due to varying input voltages relative to the LED string voltage. It is suitable for designs requiring four separate regulated outputs from one controller. Consider the wide input voltage range if the power source varies significantly. The high operating temperature rating makes it appropriate for enclosed or high-ambient environments.

LED Driver IC Part Context

This part belongs to the LT3942 series of LED drivers from Analog Devices. It is distinct from the LT3762, which is a simpler boost controller, and the LT3932, which is a synchronous buck-only driver. The HUFD#PBF designation specifies the extended temperature grade and lead-free packaging within the broader LT3942 family.
