Product details

100V LED driver controller with multi-topology flexibility

The LT3756IMSE#PBF is a DC DC controller from Analog Devices designed as a high-voltage LED driver. It supports analog and PWM dimming, making it suitable for applications requiring precise brightness control. The controller operates across multiple topologies including flyback, SEPIC, step-down (buck), and step-up (boost), giving designers flexibility in power stage architecture. With a single output rated to 100V and no internal switch, it drives an external MOSFET to handle the load current, keeping the thermal dissipation off the controller. The supply input range spans 6V to 100V, accommodating automotive battery rails, industrial 48V supplies, and high-voltage LED strings directly without an extra bias regulator. Housed in a 16-lead MSOP with exposed pad (16-MSOP-EP), the package provides a low thermal resistance path to the PCB.

It is ROHS3 compliant, meeting current environmental requirements for lead-free assembly.

Frequently asked questions

Can LT3756IMSE#PBF handle automotive temperature ranges?

Yes, the operating temperature range is -40°C to 125°C, which covers automotive under-hood and cabin requirements. It is suitable for automotive LED lighting systems such as daytime running lights, headlamps, and interior lighting.

Can LT3756IMSE#PBF be used for SEPIC topology?

Yes, SEPIC is one of the supported topologies alongside flyback, buck, and boost. This makes the part suitable for applications where the input voltage can be above or below the LED string voltage, such as automotive with a 12V battery driving a 24V LED array.

What is the closest functional equivalent to LT3756IMSE#PBF?

The LT3756EMSE-1#PBF is a functional equivalent within the same LT3756 family, sharing the same dimming options, topology support, frequency range, and temperature grade. The primary difference is the suffix indicating a different test grade or ordering option — verify the specific datasheet for any parametric deltas before substituting.
