National Semiconductor has developed an LED driver with dynamic headroom control and multiple outputs for high-power applications. The LM3464 accurately and efficiently drives up to four strings of LEDs, and is aimed at applications such as industrial, street and automotive lighting. It is a high-voltage current controller with four individual current regulator channels. The device works in conjunction with external n-channel MOSFETs and sense resistors to accurately drive current to each LED string. It features a wide input voltage range up to 80 V to drive multiple LEDs per string. The LM3464 features both PWM and analog dimming interfaces to allow the user to select between various dimming types for different applications. Protection features include VIN under-voltage lockout, LED open/short circuit and over-temperature fault signalling to the system controller.
