The LM3424-Q1 from Texas Instruments is a versatile, high-voltage N-channel MOSFET controller specifically designed for LED driver applications. It is AEC qualified for automotive use and operates within a wide input voltage range of 4.5 V to 75 V.
This controller can be configured in multiple topologies, including buck, boost, buck-boost, and SEPIC, providing flexibility for different design requirements. Key electrical features include a programmable switching frequency up to 2 MHz, PWM and analog dimming capabilities, and a 1-A peak MOSFET gate driver. It also incorporates essential protection features such as input undervoltage and output overvoltage protection, along with cycle-by-cycle current limiting.
The LM3424-Q1 includes a thermal foldback feature for effective temperature management of the LEDs, enhancing system reliability. It is housed in a 20-HTSSOP package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ).
This device is ideal for automotive LED lighting systems requiring precise current control and thermal management.
