uP1665P

2-Phase Synchronous-Rectified Buck Controller

for Mobile GPU Power

Features

General Description

The uP1665P is a 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 uP1665P adopts proprietary RCOT^TMtechnology,

providing flexible selection of output LC filter and excellent

transient response to load and line change.

The uP1665P supportsNVIDIAOpen Voltage Regulator-2

with PWMVIDfeature. The PWMVIDinput is buffered and

filtered to generate accurate reference voltage, and the

output voltage is precisely regulated to the reference input.

The uP1665P uses MOSFET R_DS(ON)current sensing for

channel current balance. The uP1665P also implements a

multi-function pin (OCS/CB) for OCP threshold selection

and current balance adjustment.

Support NVID Open VReg Type-2 PWMVID
