uP9509 - 3/2/1-Phase Synchronous-Rectified Buck Controller

Features

  • The uP9509 is a 3/2/1-phase synchronous-rectified buck controller specifically designed to work with 4.5V ~ 26V input voltage and deliver high quality output voltage for highperformance graphic processor power. The uP9509 adopts proprietary RCOTTM technology, providing flexible selection of output LC filter and excellent transient response to load and line change. The uP9509 supports NVIDIA Open Voltage Regulator-2+ with PWMVID feature. The PWMVID input is buffered and filtered to generate accu.
