Maxim Integrated Buck and Buck-Boost LED Drivers
Maxim Integrated MAX25610 LED Drivers reduce design complexity and BOM cost while improving efficiency.
The drivers have a wide operating voltage range and can tolerate load dump events up to 40V, optimal for automotive and industrial applications. The drivers use current mode control for a fast transient response, ensuring a constant output current up to 3A for consistent lighting performance.
They integrate two 60mΩ power MOSFETs, have an internal current sense option, and offer PWM dimming to minimize external component count, while a 2.2MHz switching frequency option reduces inductor size.
MAX25610 LED drivers support buck, inverting buck-boost, and boost conversion, providing the flexibility to drive LEDs for interior and exterior lighting applications.
