描述 Description

The uP1665P is a 2/1-phase synchronous-rectified buckcontroller specifically designed to work with 4.5V ~ 26Vinput voltage and deliver high quality output voltage forhighperformance graphic processor power.

The uP1665P adopts proprietary RCOTTM technology,providing flexible selection of output LC filter and excellenttransient response to load and line change.

The uP1665P supports NVIDIA Open Voltage Regulator-2with PWMVID feature. The PWMVID input is buffered andfiltered to generate accurate reference voltage, and theoutput voltage is precisely regulated to the reference input.The uP1665P uses MOSFET RDS(ON) current sensing forchannel current balance. The uP1665P also implements amulti-function pin (OCS/CB) for OCP threshold selectionand current balance adjustment.

Other features include power saving control input, and adelayed power good output. This part is available inWQFN3x3 - 20L package.
