The MAX1561ETA+ is a high precision adjustable LED driver from Maxim Integrated, an exceedingly capable and versatile integrated circuit primarily designed for driving LEDs in varied applications. This integrated circuit provides drive current ranging from 10mA to 250mA (dependent upon external components) with very small variations over wide input voltage, temperature and output current ranges. It also features a built-in error amplifier and PWM input to further increase flexibility when driving multiple LEDs.

Due to its flexible design, the MAX1561ETA+ LED driver is perfect for a wide range of LED applications, such as lighting fixtures, LCD backlighting, automotive lighting, stage lighting, and more. It also has an excellent efficiency, up to 96% in certain applications, which makes it well suited for driving high-power LEDs down to very low current levels.

The core of the MAX1561ETA+ is an automobile-rated linear current regulator with precise current control. The MAX1561ETA+ utilizes an external resistor to precisely calibrate the precise current levels. The precise current setting from the resistor can be adjusted to obtain very precise current settings from one led to the next.

In addition to its precise current settings, the MAX1561ETA+ also includes a built-in error amplifier and PWM input, allowing for precise current switchers and dimmers when driving multiple LEDs. It also includes an adjustable soft start feature prevents LEDs from resetting themselves during power up. The MAX1561ETA+ is also designed to be an automotive-grade device, making it suitable for use in lighting fixtures in passenger vehicles.

In addition to LED driving applications, the MAX1561ETA+ can be used for other applications such as motor control, DC to DC converters, and battery chargers. Its ability to precisely control current makes it well suited for each of these applications.

The MAX1561ETA+ LED driver is a flexible and efficient integrated circuit for driving LEDs for a variety of applications. It is highly precise, thanks to its built-in error amplifier, PWM input, and adjustable current setting from the external resistor. It is also automotive-grade, making it suitable for use in passenger vehicles as well as other applications such as motor control, DC to DC converters, and battery chargers. It is an ideal IC for driving LEDs with very small variations over a wide range of input voltage, temperature, and output current levels.
