PMIC - Laser Drivers: NT28L90-QFN Application Field and Working Principle

NT28L90 is a laser driver developed by Nantronix and distributed in QFN package. It is a wide range of laser drivers and laser driver application solutions for a variety of optical and photonic devices, from small to large scale. It has a range of selectable input and output drivers for the convenience of the designer, with output drivers supporting laser diode operation up to 0.25 A and 3 V. Its wide dynamic range and adjustable output voltage allow it to be used in many applications.

Generally, NT28L90 can be used in many application fields, such as in optical communication, laser display, industrial automation, military, biomedical instrumentation and high-speed imaging, etc. In optical communication, it is used to provide bias to lasers that are able to transmit data at high speeds. In laser display, the device is used to pass current to the laser diode, allowing the display to be presented on a large area, so that viewers can clearly see the content. Also, in industrial automation, NT28L90 can control laser sensors or laser cutting/processing systems, providing better automation and accuracy.

NT28L90 is a multi-channel laser driver and comes with a power supply regulator, so it can withstand a wide range of output voltages. It has a wide operating range, plus adjustable voltage and current for maximum efficiency. Additionally, the driver is easy to manufacture, as it has low power consumption and requires fewer components. This helps make the device less expensive.

The working principle of NT28L90-QFN is based on the optical amplification effect of lasers. When the current is passed through the laser diode, the electrons transfer their energy to the atoms inside the device, generating an optical substantial energization (OSE). This energy difference between the electrons and the atoms cause a symmetrical diffusion of electrons and photons, which then propagate in a straight direction. The number of photons generated is proportional to the current supplied. This is used to control the brightness of the laser source.

The NT28L90-QFN laser driver also has an in-built power controlling system which is optimized for the most efficient energy transfer. This helps reduce power losses and maintains a constant output voltage and current. The driver also contains indicator LEDS which indicate the ON/OFF state of the device.

In summary, NT28L90-QFN is a multi-channel laser driver used in many application fields. It has a wide operating range, adjustable voltage and current as well as a power controlling system for maximum efficiency. And it has indicator LEDS for easy monitoring. It is an ideal choice for those looking for an efficient, highly reliable and cost-effective laser driver.
