uP9510 3/2/1-Phase Synchronous-Rectified Buck Controller for GPU Power General Description The uP9510 is a 3/2/1-phase synchronous-rectified buck controller specifically designed to work with 10.8V ~ 13.2V input voltage and deliver high quality output voltage for high-performance graphic processor power. The uP9510 adopts proprietary RCOTTM technology, providing flexible selection of output LC filter and excellent transient response to load and line change. The uP9510 supports NVIDIA Open Voltage Regulator2+ with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate reference voltage, and the output voltage is precisely regulated to the reference input.
