MAX1984ETP+T is a PMIC – LED Drivers, specifically designed to drive light source arrays such as light emitting diodes (LEDs) in flat-panel displays, automotive applications, and general lighting. PMIC – LED Drivers serve as the interface between an LED driver IC and the LED source, by supplying a steady current to the LED source while eliminating power losses due to LED mismatching across a range of forward voltages.

PMIC – LED Drivers provide up to 8 LEDs with a constant current, allowing customers to improve the display brightness and color uniformity by maintaining the same current across multiple LEDs. To achieve this, it requires driving the LEDs with a consistent current level. The MAX1984ETP+T uses a single or dual-port synchronous DC/DC step-down switching regulator to precisely regulate the current and provide improved line and load regulation. This device also offers low output voltage ripple, achieving better picture quality.

The MAX1984ETP+T offers a wide set of constant current and adjustable current settings, allowing customers to drive up to 8 LEDs in various configurations. It supports current levels ranging from 20mA to 250mA, and includes a wide set of feature options such as adjustable output current, adjustable monitoring, power up/down sequencing, and soft-start/soft-stop features. This device also can be used in a wide variety of applications and supports many different types of output power configurations.

The MAX1984ETP+T is designed to operate with a wide input voltage range of 4.5V to 18V, and delivers the regulated output current over the operating temperature range of -40°C to +125°C, enabling rugged designs and wide range applications. This devices also provides ample protections for the LEDs, controlling any fault conditions and protecting devices from damage.

The MAX1984ETP+T supports constant current regulation and accurate current regulation over the entire regulated output current range. It also features current slew rate control, which provides more accurate current regulation while maintaining a low ripple voltage at the LED output. Additionally, it provides a duty cycle control mode to limit the LED current in transient moments during power up/down.

The MAX1984ETP+T can be used in a variety of applications, including LCD TVs, IPTVs, monitors, automotive instrument clusters, backlighting for industrial and medical imaging displays, automotive LCDs, general lighting, and any other application that requires constant current control and accurate current regulation.

The MAX1984ETP+T is a cost-effective and highly efficient device designed to simplify and reduce development time for LED applications, while allowing customers to benefit from increased system efficiency, long-term reliability, and product lifetime.
