Product Summary
The SI9140CY-T1 is a high-performance, surface-mount switchmode controller made to power the new generation of low-voltage, high-performance microprocessors. The SI9140CY-T1 has an input voltage range of 3 to 6.5 V to simplify power supply designs in desktop PCs. Its high-frequency switching capability and wide bandwidth feedback loop provide tight, absolute static and transient load regulation. Circuits using the SI9140CY-T1 can be implemented with low-profile, inexpensive inductors, and will dramatically minimize power supply output and processor decoupling capacitance. The SI9140CY-T1 is designed to meet the stringent regulation requirements of new and future high-frequency microprocessors, while improving the overall efficiency in new green systems.
