uP1651Q

2/1-Phase PWM Controller with SVID for VR12.5

Features

General Description

The uP1651Q is a VR12.5 compliant PWM controller that Intel VR12.5 Compliant

surpports 2/1-phase operation. This device integrates 2

Output Current and Thermal Reporting

Programmable ICCMAX,VBOOT

MOSFET gate drivers with embedded bootstrap diode to

minimize external component count. To comply with

VR12.5 specification, the uP1651Q accurately reports RCOT^TMControl Topology

output current and VR temperature.

Easy Setting

The uP1651Q provides programmable 2/1 phase

operation. uP1651Q integrates 2 bootstrapped drivers that

support 12V + 12V driving capability. 2/1 phase operation

is enabled by a logic level ISENx output, achieving optimal

balance between cost and flexibility.

Smooth Mode Transition

Fast Transient Response

Selectable 2/1-Phase Operation

Differential Remote Voltage Sensing

The uP1651Q supports automatic phase adding/dropping

that is activated by PSI command from SVID or H/W PSI

setting. The uP1651Q operates in diode emulation mode

at extreme light load condition, yielding maximum

efficiency over entire load current range.

Other features include adjustable soft start, under/over

voltage protection, over current protection and thermal

shutdown. The uP1651Q is available in WQFN4x4-32L.
