MAX16824EUE+

MAX16824EUE+ is a general purpose PMIC - LED drivers optimized for driving high power LEDs for a variety of consumer, industrial, and automotive lighting applications. This device is a bidirectional step-down constant current controller that allows biasing of one or two LEDs from a single input. This device requires up to 40V input voltage and integrates a 400mA high-side switch with an adjustable current limit for single-string applications.

It also offers protection from over-voltage, over-temperature, and over-current conditions. Its unique design provides excellent power efficiency while maintaining low EMI and noise. The MAX16824EUE+ can be used in both step-down and step-up configurations, allowing for better control of the system voltage in the event of fluctuating input voltages. With a OVLO (Over Voltage Lockout) feature, the LED current can be monitored in both LED strings, allowing for safe operation with minimal failure.

The MAX16824EUE+ is able to provide high-efficiency drive performance with a minimum of external components. It operates with a wide input range of 3.2V to 36V and a power range of 1W to 10W. Internal overload and over temperature protection are provided using N-MOSFET linear feedback circuitry. In addition, an external resonant inductor is used to precisely regulate the LED current.

MAX16824EUE+ achieves its high efficiency by using a buck-boost architecture. The switching frequency is adjustable from 500kHz to 2MHz, allowing for customizing the efficiency of the system for various applications. The device is also optimized for lowripple operation and low EMI. With its current control chip, the MAX16824EUE+ is able to offer an optimized balance between system cost and efficiency.

MAX16824EUE+ is very simple to configure and operate. The device utilizes an external clock input that can be synchronized to the input power supply, allowing the device to be automatically powered up or powered down. The device includes a programmable gate driver with four selectable delay settings, allowing the user to fine-tune the system performance. The device also includes an internally switchable soft-start feature, allowing faster system start-up with minimal LED flicker.

MAX16824EUE+ is suitable for a variety of consumer, industrial, and automotive lighting applications. The device can be used for general lighting, signage and displays, and automotive headlights. With its low power consumption and high-efficiency, it is ideal for use in energy efficient lighting systems. The device also offers a lockout feature to prevent excessive LED current in the event of overvoltage or over-temperature.

In conclusion, the MAX16824EUE+ is an excellent device for driving high power LEDs. It offers high-efficiency, protection from over-voltage and over-temperature, as well as low-ripple operation and low EMI. With its adjustable current limit and adjustable switching frequency, it is optimal for a wide range of consumer, industrial, and automotive lighting applications.
