LEDs (Light Emitting Diodes) are the most power-efficient and long-lasting lighting option around. As such, they are becoming increasingly popular for a wide range of lighting applications, from home lighting to industrial lighting. The XR46083EHTR-ADJ is a high-efficiency, low-power PMIC (Power Management Integrated Circuit) designed specifically for LED drivers. This application field and its working principle are discussed below.

Applications of XR46083EHTR-ADJ

The XR46083EHTR-ADJ is designed to be used as a constant-current regulator in LED drivers. It is optimized for driving multiple strings of LEDs, and can support up to 8 strings of LEDs connected in series. It has a wide range of operating voltages (ranging from 4.5 V to 65 V), making it suitable for a wide range of applications, from automotive lighting to consumer lighting. The XR46083EHTR-ADJ is also optimized for efficiency, providing up to 96% efficiency. Furthermore, it is low power, with a maximum operating current of 2.5 A.

XR46083EHTR-ADJ Working Principle

The XR46083EHTR-ADJ is based on a switched mode power supply (SMPS) topology, which allows for efficient power conversion. The XR46083EHTR-ADJ is able to regulate a constant current over a wide input voltage range, and is also able to maintain the current over a wide temperature range. The XR46083EHTR-ADJ’s regulation loop continuously monitors the output current and adjusts the duty cycle of the switch as necessary to maintain constant current into the LEDs.

The XR46083EHTR-ADJ also features a built-in shutdown delay feature to protect the LEDs from inrush current. The XR46083EHTR-ADJ also features various protection features, including overtemperature protection and open circuit protection, which help prevent the device from failure in the event of a fault condition.
