3/2/1-Phase Synchronous-Rectified Buck Controller for GPU Power Supply
General Description
Features
The uP9529Q is a 3/2/1-phase PWM controller specifically designed to work with 3V ~ 20V input voltage and deliver high quality output voltage for high performance graphic processor power.
The uP9529Q adopts proprietary RCOTTM technology, providing flexible selection of output LC filter and excellent load transient response. The uP9529Q supports NVIDIA Open Voltage Regulator type 3i+ with PWMVID interface. The PWMVID input is buffered and filtered to generate accurate reference voltage and the output voltage is precisely regulated to the reference input.
The uP9529Q is capable of...
