Frequently Asked Questions
What LED driver topology does MAX20078AUE+ implement, and how does it improve efficiency over non-synchronous designs?
The MAX20078AUE+ implements a synchronous buck (step-down) controller topology, which replaces the freewheeling diode with a synchronous rectifier MOSFET. This reduces conduction losses across the power path, typically improving efficiency by 2% to 5% at high LED currents compared to non-synchronous buck designs. This efficiency gain is especially significant in automotive 12V LED driver applications where thermal management is critical.
How many LED channels does MAX20078AUE+ control, and what output configuration does it use?
The MAX20078AUE+ supports 2 LED segments with open-drain outputs, allowing each output to independently switch LED strings for separate brightness control. The open-drain configuration is compatible with high-side LED driver stages, enabling flexible LED string configurations for automotive DRL, turn signals, or dual-zone industrial luminaires requiring independently dimmable channels.
What is the package type of MAX20078AUE+ and what supply voltage is it designed for in automotive LED applications?
The MAX20078AUE+ is housed in a 16-pin TSSOP package measuring 4.4mm × 4.4mm, offering a compact layout for automotive LED driver PCBs. It is designed to operate from automotive 12V bus supplies, with the synchronous buck controller producing regulated LED current outputs from the higher input voltage. This makes it suitable for direct connection to automotive battery rails in both 12V and 24V LED lighting systems.
