uP9509S

3/2/1-Phase Synchronous-Rectified Buck Controller

for Mobile GPU Power

Features

General Description

The uP9509S is a 3/2/1-phase synchronous-rectified buck Support NVIDIA’s Open VReg Type-2+ PWMVID

controller specifically designed to work with 3V ~ 26V input

voltage and deliver high quality output voltage for high-

performance graphic processor power.

The uP9509S adopts proprietary RCOT^TMtechnology,

providing flexible selection of output LC filter and excellent

transient response to load and line change.

Technology

Wide Input Voltage Range 3V ~ 26V

Robust Constant On-Time Control

3/2/1 Phase Operation

Two Integrated MOSFET Drivers with Shoot-

Through Protection and Internal Bootstrap

Schottky Diode

The uP9509S 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.

Adjustable Current Balancing by R_DS(ON)Current

Sensing

Adjustable Operation Frequency

External Compensation

The uP9509S integrates two bootstrapped MOSFET gate

drivers and one PWM output achieving optimal balance

between cost and flexibility. The uP9509S uses MOSFET

R_DS(ON)current sensing for channel current balance.

Dynamic Output Voltage Adjustment

Adjustable Per-Phase Over Current Limit

Adjustable Soft-Start Time

Other features include accurate and reliable over current

limit protection, adjustable on-time setting, power saving

control input, and power good output. This part is available

in a VQFN4x4 - 24L package.
