uP9509
Description Features The u P9509 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 u P9509 adopts proprietary RCOTTM technology, providing flexible selection of output LC filter and excellent transient response to load and line change. The u P9509 supports NVIDIA Open Voltage Regulator-2+ 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. The u P9509 integrates two bootstrapped MOSFET gate drivers and one PWM output achieving optimal balance between cost and flexibility. The u P9509 uses MOSFET R current sensing for channel current balance. DS(ON) Other features include accurate and reliable over current limit protection,...
