Conclusion

The Zilker power management solution has good performance (high-speed conversion, high efficiency, 1% output accuracy, fast transient response), flexibility and ease of use (pin strapping, resistor setting or setting through SMBus, no programming required, 1 device for many applications, online design tools simplify circuit design) and smaller size (fewer discrete components, elimination of power management chips ). The Zilker solution is a complete and easy-to-use power management solution.
