PMIC - Voltage Regulators - DC DC Switching Regulators

DC DC switching regulators are a key component of modern systems. For this reason, it is important to understand the basic application fields and working principles of such systems. The SP6660EP-L is an example of a DC DC switching regulator family that can be used in a wide range of applications from industrial and automotive to consumer electronics, including motor control, power conditioning, power conversion, and power factor correction.

Applications

The SP6660EP-L is the first switching regulator family with dual buck-boost regulated outputs. This feature makes it ideal for applications with wide input ranges and for those facing the challenge of providing inrush current protection or power factor correction. Additionally, due to its high efficiency, the SP6660EP-L is well suited for high power applications such as automotive, industrial, and medical. It is also suitable for telecommunications and computing systems as its low components count, high switching frequency and integration make it one of the highest performing power solutions in the market today.

Working Principle

The SP6660EP-L utilizes a dual buck-boost topology, commonly referred to as free-running. The free-running topology allows the output voltage to be adjusted over a wide range, from 0.9V up to 6V, with a single external resistor. This makes it ideal for applications requiring high accuracy and flexibility in output voltages.The SP6660EP-L also features a unique on-time control scheme. This allows for improved immunity against line transients and noise, as well as optimized robustness and reliability with low-cost external components. In addition to on-time control, the SP6660EP-L also has a proprietary compensation technique. This ensures accurate, stable, and constant output voltage during line and load transients.The high switching frequency of the SP6660EP-L allows designers to minimize the size and cost of external components. This, coupled with its high efficiency, makes it suitable for applications with limited space or cost. The SP6660EP-L also features a variety of advanced features, such as adjustable switching frequency and adaptive on-time control.

Conclusion

The SP6660EP-L is a powerful and highly efficient DC DC regulator family with a wide range of applications. It utilizes a dual buck-boost topology, on-time control, and a proprietary compensation technique to ensure accurate, stable, and constant output voltages. Additionally, its high switching frequency enables the designer to minimize the size and cost of external components, while its adaptive on-time control ensures improved immunity against line transients and noise. The SP6660EP-L is an ideal solution for applications requiring high accuracy, flexibility, and performance.
