Analog Devices / Maxim Integrated MAX25610x Buck & Buck-Boost LED Drivers

Analog Devices MAX25610x Synchronous Buck and Buck-Boost LED Drivers provide constant output current to drive high-power light-emitting diodes. The drivers are found in automotive and industrial lighting applications requiring high-voltage input. The drivers integrate two 60mΩ power MOSFETs for synchronous operation, minimizing external components. The devices' flexible configuration supports buck, inverting buck-boost, and boost conversion. The LED drivers incorporate current-mode control, providing a fast transient response and eases loop stabilization. Analog Devices MAX25610x Synchronous Buck and Buck-Boost LED Drivers can also be used as a DC-DC converter using the FB input as feedback for the output voltage divider.
