It is a monolithic IC with high efficiency, wide input range and adjustable current output, designed for improving the performance of laser diode, LED and other light sources. This driver belongs to the PMIC - Laser Drivers family, and its application field is diverse, involving various off-grid and industrial models. This article will discuss the working principle and application field of the ONET1151LRGET.The ONET1151LRGET is a linear regulator driver for laser diodes, and it is commonly used in off-grid and industrial applications. It provides an output of up to 3A, a wide input range of 4V to 18V DC, and integrated protection against over-current, over-temperature and reverse voltage events. The device is ideal for driving laser diode, LED and other illumination in industrial, medical and electronic applications such as 3D printing.The working principle of the ONET1151LRGET driver is simple. The input voltage supply is connected in one end to the control circuit on the driver, while the other side is connected to the load. When an alternating current is generated, it creates electrical oscillations that cause a wave pattern. This wave pattern then eliminates excess current in the supply and limits the output current to a specific preset value. The wave pattern has several beneficial features. Firstly, it reduces the risk of overheating of the supply, thus preventing it from malfunctioning or being damaged. Secondly, the intensity of the wave pattern can be used to regulate the output current, allowing precise control of the laser diode. Thirdly, the pattern of the wave helps to minimize the inrush current, which is beneficial for controlling the illumination of the LEDs and laser diodes.The ONET1151LRGET driver has several advantages over conventional drivers. Firstly, it is simple and efficient, using energy more efficiently and reducing power consumption. Secondly, the built-in protection features help to keep the system safe from over-current, over-temperature and reverse voltage events. Thirdly, the adjustable output current allows for precise control of the laser diode or LED. Finally, the wide input range makes the driver ideal for off-grid and industrial applications.In conclusion, the ONET1151LRGET driver is an efficient and versatile laser diode driver for off-grid and industrial applications. It has a wide input range, adjustable output current and integrated protection against over-current, over-temperature and reverse voltage. The device is easy to use and has several advantages over conventional drivers, making it an ideal choice for improving the performance of laser diodes and other illumination devices.
