The MAX5019CSA+ is a highly integrated, high-voltage programmable current source designed for precision LED (Light Emitting Diode) current control applications. Its compact size and numerous features make it ideal for a variety of lighting applications.
One of the key features of the MAX5019CSA+ is its ability to deliver a constant current to an LED load, regardless of fluctuations in the supply voltage. It can operate with a wide input voltage range of 6V to 76V, making it compatible with various power sources.
The MAX5019CSA+ offers a programmable output current up to 1.2A using a simple external resistor. This flexibility allows for easy adjustment of the LED brightness. The device also includes built-in thermal shutdown and current foldback protection, ensuring safe operation even in demanding conditions.
With an integrated PWM (Pulse Width Modulation) dimming function, the MAX5019CSA+ enables precise control of the LED brightness by adjusting the duty cycle of the input signal. This feature is particularly useful for applications where dynamic lighting effects or dimming scenarios are required.
In order to optimize LED efficiency and minimize power losses, the MAX5019CSA+ incorporates a low-dropout voltage regulator for internal power supply generation. This results in improved energy efficiency and reduced heat dissipation compared to traditional linear regulators
