The output voltage can also be adjusted through the use of an external feedback resistor divider. The LM2593HVSX-5.0/NOPB can be used as a stand-alone regulator or as part of a larger system, integrating several devices together to regulate a number of different voltages. The LM2593HVSX-5.0/NOPB has a very small footprint that is less than three square millimeters, allowing it to fit in the tightest of spaces. The device also features a control pin, meaning that each device can be individually tuned for optimal performance. The LM2593HVSX-5.0/NOPB is available in a range of different packages, including SOIC-8 and TSSOP-14, making it suitable for a wide range of applications.

Working Principle

The LM2593HVSX-5.0/NOPB is a synchronous buck regulator with a wide input voltage range, low quiescent current and fast transient response. The device operates by using an internal voltage regulator to maintain the output voltage. The voltage regulator is switched on and off in order to maintain the desired output voltage. This process is known as Pulse Width Modulation (PWM). When a Pulse Width Modulation signal is sent to the regulator, the output voltage of the device is adjusted by varying the amount of power delivered. The regulator takes input power and converts it into a clean output voltage. The output voltage is then regulated to maintain a steady level regardless of changes in the input voltage. To maximize efficiency, the LM2593HVSX-5.0/NOPB also features a selectable current limit value. This feature helps to minimize the possibility of output voltage droop and improves the overall efficiency of the regulation process. The device features a wide range of fixed output voltages, ranging from 0.6V to 6V. The LM2593HVSX-5.0/NOPB also includes a voltage sense terminal that can be utilized to sense the output voltage and help fine-tune the setting of the device. It can also be used to adjust the current limit value, allowing the LM2593HVSX-5.0/NOPB to provide optimal regulation performance in any given application.

Conclusion

The LM2593HVSX-5.0/NOPB is a voltage regulator designed for high-performance and efficient point-of-load voltage regulation. It offers high current output accuracy, adjustable frequency and a wide selection of loop gain values. The device is of a small footprint and is highly efficient. It can be used as a stand-alone, or integrated into a larger system, providing an ideal solution for applications requiring a small footprint, high efficiency, and excellent performance.
