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 RCOT^TM 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 supporting two types of applications, the advanced DrMOS power module with current reporting function, and the inductor DCR current sensing application. The integrated power saving input (PSI) allows for graphic processors to control the operating phase number to obtain high efficiency in light load condition.

Other features include adjustable switching frequency, adjustable soft-start time, channel current limit, under voltage protection, over voltage protection and power good indication. The uP9529Q is available in a WQFN3x3-20L package.
