LM3424 Description

Short technical summary and product information.

The Texas Instruments LM3424 is a high-voltage N-channel MOSFET controller specifically designed for driving LEDs. It offers flexibility by supporting buck, boost, buck-boost, and SEPIC topologies, making it suitable for a wide range of illumination applications.

Key electrical specifications include an input voltage range from 4.5 V to 75 V, an output voltage capability up to 72 V, and a maximum output current of 5 A. The device features a high-side adjustable current sense for tight regulation and efficiency. It also includes a 2-ohm, 1-A peak MOSFET gate driver and a precision 2.45V voltage reference.

For enhanced thermal management, the LM3424 incorporates a programmable thermal foldback feature. It also supports PWM and analog dimming methods. The controller operates over a wide temperature range of -40°C to 125°C and can be configured for adjustable switching frequencies up to 2.0 MHz, with external synchronization capabilities.

The LM3424 is available in a 20-pin HTSSOP package. Its robust feature set, including input undervoltage and output overvoltage protection, cycle-by-cycle current limit, and programmable soft-start, makes it an ideal choice for general illumination, indoor and outdoor SSL, and constant-current regulator applications.
