Maxim Integrated MAX16833EAUE+T High-Efficiency LED Driver
The MAX16833EAUE+T from Maxim Integrated is a high-performance, high-brightness LED (HB LED) driver designed to deliver constant current to drive strings of LEDs in a wide array of lighting applications. This versatile driver integrates a high-side current-sense amplifier, a PWM dimming MOSFET, and a comprehensive protection circuitry, all of which contribute to its robustness and reliability in demanding lighting systems.
With an input voltage range of 4.75V to 28V, the MAX16833EAUE+T is suitable for automotive, industrial, and architectural lighting systems. It can be configured for either boost, buck-boost, or SEPIC topologies, providing design flexibility to accommodate various LED configurations and power requirements. The driver supports a wide range of external PWM dimming frequencies, allowing precise control over the brightness levels of the LED array.
The MAX16833EAUE+T boasts an integrated 5V regulator, which can be used to power external circuitry or as a voltage reference. Its high-side current sensing allows for the detection and regulation of the LED current without the need for a low-side sense resistor, thereby reducing power loss and improving efficiency.
Protection features of the MAX16833EAUE+T include cycle-by-cycle over-current protection, thermal shutdown, and open/short LED detection. These protective measures ensure the longevity of the LED driver and the lighting system it powers. The device also provides a fault-indicator output to signal the presence of fault conditions to the host system.
Available in a compact, thermally efficient 16-pin TSSOP-EP package, the MAX16833EAUE+T is designed to minimize the footprint on the PCB and simplify the thermal management of the LED driver. This product is also offered in a tape and reel format, marked with the "+T" suffix, which is ideal for automated manufacturing processes, ensuring a streamlined production flow.
Overall, the MAX16833EAUE+T from Maxim Integrated is a highly adaptable and efficient solution for powering high-brightness LEDs with the added benefits of advanced protection features and design flexibility.
