The LX7302CLQ is a monolithic integrated circuit dedicated to DC-DC switching control. Taking advantage of its integrated low-side switch, high-side switch, and bootstrap circuit, the LX7302CLQ allows for a more compact design than other DC-DC switching controllers. As such, designers are able to utilize this chip without the need for additional components. In addition, the LX7302CLQ also boasts a wide range of features, making it a highly reliable and versatile device.

Given its range of features, the LX7302CLQ has a wide range of application fields. Designers can use the LX7302CLQ for a variety of DC-DC topologies, including buck, boost, and buck-boost configurations. Additionally, the low-side and high-side switches support peak current ratings up to 1.5A and 0.8A, respectively, making it suitable for low to medium power applications. Additionally, the LX7302CLQ is capable of working within voltage input ranges of 4.5V up to 28V.

The LX7302CLQ is equipped with an array of features to provide reliable and efficient operation. The integrated soft-start sequencer can be externally adjusted to provide a controlled startup ramp. Including an adjustable frequency ranging up to 1MHz, designers can precisely tune the LX7302CLQ to ensure optimal operation. Additionally, the LX7302CLQ is designed with a low current standby mode, which reduces overall power consumption. This feature is further complemented by built-in undervoltage lockout and overtemperature protection.

At the core of the LX7302CLQ lies its working principle. The LX7302CLQ works in synchronous buck configuration, allowing the power MOSFET to turn on and off simultaneously to control the output voltage. This works by the LX7302CLQ issuing a duty cycle signal to the MOSFET based on the current input and output voltage. This in turn causes the power MOSFET to re-adjust its duty cycle depending on the power demand of the application.

The LX7302CLQ is a highly reliable and efficient DC-DC switching controller. It is well suited for a range of DC-DC topologies and is capable of handling a wide range of input and output voltages. Furthermore, its range of features allows designers to create reliable and efficient power designs. This makes the LX7302CLQ an excellent choice for use in a variety of applications.
