The Texas Instruments LM3407 is a versatile constant current output floating buck switching converter specifically designed for driving high-power LEDs. It is well-suited for automotive, industrial, and general illumination applications.
The device features an integrated N-channel MOSFET, simplifying the application solution. The output current accuracy is maintained within 10% through an external resistor. The switching frequency can be adjusted from 300 kHz to 1 MHz, offering design flexibility. It includes independent device enable and PWM dimming control for brightness adjustment, as well as input undervoltage lockout (UVLO) and thermal shutdown protection for robustness.
The LM3407 is available in an MSOP-8 PowerPAD package, which provides excellent heat dissipation. This package is suitable for surface mounting.
Key electrical specifications include an input operating range of 4.5 V to 30 V and an output voltage range of 0.1 VIN to 0.9 VIN. The typical quiescent current is 0.78 mA, and the maximum output current is 0.35 A. The operating temperature range is -40°C to 125°C.
