The LX1672-03CLQ is a DC-DC switching controller designed by ON Semiconductor. It has a wide range of applications, ranging from industrial to automotive grade, as well as it can be used in multiple power regulation environments. Additionally, it features a wide input voltage range with excellent accuracy and regulation over the full load range.

The LX1672-03CLQ has a current-mode design, meaning that the output is regulated by controlling the amount of energy flowing through the device. This is done through sensing the load current, which then is converted into a control signal and used to drive the power FET switch. With this control method, the output voltage is well regulated and fast transient responses.

The LX1672-03CLQ is optimized to suit different applications, including those requiring a higher level of performance. It has an adjustable operating frequency, enabling the device to be used with a wide variety of FETs and inductors. Furthermore, it includes a soft-start feature that prevents overshoot when the device is initially powered up. This feature helps to keep the current demand on the 5V line during start-up within limits.

The LX1672-03CLQ also has a wide range of protection features, such as over-voltage, under-voltage, overload, over temperature protection. Moreover, the device includes a precision internal DAC to ensure excellent accuracy over the full load range. It offers the capability to detect both input voltage and output voltage, as well as being able to prioritize either one. This helps in monitoring and protecting the entire system, while still providing fast transient response.

The LX1672-03CLQ is designed to provide robust and reliable performance with an exceptional level of system protection. It is ideal for automotive and cost-sensitive applications, such as infotainment systems, backup camera systems, and GPS navigation systems. Furthermore, due to its wide input voltage range and its precision accuracy, it is also suitable for industrial applications.
