The LX7165-02CSP can provide up to 1.5A output current, and the operating input voltage range stretches from +4V to +30V. Its adjustable output voltage can range from +0.8V to +5V.

Application Field

The LX7165-02CSP DC-DC switching regulator is typically used as a power source for embedded devices such as FPGAs, analog to digital converters, DSPs, digital signal processors, etc. It can also be used for powering various communication systems, digital displays, portable electronics, and many other applications related to power conversion. The variety of features and benefits makes the LX7165-02CSP an attractive choice for these purposes.

Working Principle

The LX7165-02CSP is an interleaved DC-DC switching regulator, which is based on the principle of multiple switching stages connected in series. This arrangement allows for a high conversion efficiency. The interleaving helps to minimize the voltage ripple components induced by switching, thus resulting in a regulated output voltage with a low noise level. The LX7165-02CSP is capable of achieving high levels of conversion efficiency, due to the use of two separate switching paths, each with its own independent driver. These parallel current paths enable simultaneous high-current switching and reduce power dissipation and power losses, compared to single-path switching.

The onboard ICs used in the LX7165-02CSP includes an analog to digital converter (ADC), which provides precise control and monitoring of output levels. The integral control loop in the LX7165-02CSP relies on the ADC to ensure accurate regulation of the output voltage. The DC-DC switching regulator also features a precise current limit protection that limits the current output up to the rated value, in order to protect against overloading.

Additionally, the LX7165-02CSP is housed in a compact 9mm × 11mm surface-mount package, which allows for easy integration and a fast assembly process. The device can also be programmed using its I2C interface for advanced monitoring and control of the output voltage.

Conclusion

The LX7165-02CSP DC-DC switching regulator is an excellent choice for applications that require a reliable power source with a long rated operating temperature range of -40°C to +125°C. Its advanced features, efficiency, small size and flexible programming capabilities make it a great performer in extreme environments.
