MAX6968AUE+

The MAX6968AUE+ is a constant-current output, multimode LED driver from Maxim Integrated, designed specifically for Solid State Lighting applications. It offers a range of features which make it an ideal device for modern day LED lighting applications, such as linear and constant current operation, active-low power-on/off control, and adjustable frequency up to 500kHz.

The device combines an LED driver with a configurable input voltage regulation to simplify applications and reduce design complexity. Integrating all the necessary circuit components into a single device, it enables a fast and cost-effective design. In addition, it provides a wide range of features, such as short-circuit protection, over-temperature control, and low-power sleep mode, all designed to minimize system downtime and power dissipation.

The MAX6968AUE+ is designed for high power LED applications and is capable of driving up to 400mA per LED string in constant-current mode. It offers both linear and constant current LED dimming control, enabling it to drive LEDs with a wide range of operating voltages, from 10V to 36V. Its operating frequency is adjustable from 10kHz to 500kHz, allowing for a wide variety of design options and flexibility.

The MAX6968AUE+ operates in constant-current mode, which ensures that the LEDs receive the exact current necessary for proper operation. In order to maintain the constant current, the device senses the voltage across each LED string and adjusts the current accordingly. The device also features over-temperature protection, which will shut off the device in the event that the temperature exceeds the safe operating limit for the LEDs. The device also supports active-low power-on/off control, allowing for easy powering of the device and saving power by disabling the device when not in use.

The MAX6968AUE+ provides excellent cost and power savings in LED applications, while also offering the flexibility to customize designs to meet specific needs. With its wide range of features, it’s an ideal device for powering and controlling high power LEDs. It is a great choice for applications such as street lighting, signage lighting, auto lighting, and industrial lighting.
