The X9522V20I-A is a configurable laser driver in the Power Management Integrated Circuit (PMIC) family. It is designed to maximize output power and reliability while providing a range of features including programmable pulse width, pulse height, pulse repetition, and voltage regulation. The device is capable of driving lasers with a maximum output power of 4.95A and a maximum operating voltage of 37V. Its high linearity regulated current control circuit, makes it suitable for operating directly in feedback configurations, with low noise, and no additional external components.

This PMIC laser driver is based on a Field Effect Transistor (FET) and has a switching frequency of up to 200kHz. It offers a wide input voltage range of 2.5V to 36V and a wide output voltage range of 0V to 36V. The output power can be further adjusted by a step up or down converter. The device also provides thermal protection, fault detection and a circuit protection feature, in order to protect the device from potential fault conditions or incorrect circuitry.

The X9522V20I-A’s application field covers a wide range of lasers, from the low cost single wavelength laser, through to the very high power and slightly more expensive colour lasers. This is because the power supply design and output current can be tailored to the specific laser. Additionally, the device has built-in driver circuitry to ensure reliable and consistent operation of the laser over a wide range of operating conditions. This, along with its wide input voltage range, ensure the device is suitable for a wide range of applications.

The X9522V20I-A laser driver is based on two main operating principles; current regulation and voltage regulation. In current regulation, the device uses a feedback loop to monitor the output current, with current feedback signals that are proportional to the output current. When the output current exceeds a predetermined threshold, the feedback signal is corrected and the device shuts down its output. Conversely, when the output current is below the threshold, the feedback signal increases, thus allowing the device to re-enable its output.

In voltage regulation, the device uses an internal voltage reference, allowing it to constantly monitor the output voltage. When the output voltage exceeds a predetermined threshold, the device shuts down its output, or regulates its output according to the parameters set by the user. When the output voltage falls below the threshold, the device will re-enable its output.

The X9522V20I-A is a powerful and highly sophisticated PMIC laser driver which is ideal for a wide range of high power laser applications. It offers a wide range of features and a high degree of accuracy and safety through its current and voltage regulation capabilities. The device also offers an additional range of protection features, ensuring reliable operation of the device over a wide range of operating conditions. This makes it an ideal laser driver for a wide range of applications.
