SLUSAQ2 –JANUARY 2012

Dual-Channel (3-Phase CPU/1-Phase GPU) SVID, D-CAP+™ Step-Down Controller for

IMVP-7 V_COREwith Two Integrated Drivers

FEATURES

DESCRIPTION

•

Intel IMVP-7 Serial VID (SVID) Compliant

Supports CPU and GPU Outputs

CPU Channel 1, 2, or 3 Phase

Single-Phase GPU Channel

The TPS51640A, TPS59640 and TPS59641 are

dual-channel, fully SVID compliant IMVP-7 step-down

controllers with two integrated gate drivers. Advanced

control features such as D-CAP™+ architecture with

overlapping pulse support (undershoot reduction,

USR) and overshoot reduction (OSR) provide fast

transient response, lowest output capacitance and

high efficiency. All of these controllers also support

single-phase operation for light loads. The full

compliment of IMVP-7 I/O is integrated into the

controllers including dual PGOOD signals, ALERT

and VR_HOT. Adjustable control of V_COREslew rate

and voltage positioning round out the IMVP-7

features. In addition, the controllers' CPU channel

includes two high-current FET gate drivers to drive

high-side and low-side N-channel FETs with

exceptionally high speed and low switching loss. The

TPS51601 or TPS51601A driver is used for the third

phase of the CPU and the GPU channel.

•

Full IMVP-7 Mobile Feature Set Including

Digital Current Monitor

•

8-Bit DAC with 0.250-V to 1.52-V Output Range

Optimized Efficiency at Light and Heavy Loads

V_COREOvershoot Reduction (OSR)

V_COREUndershoot Reduction (USR)

Accurate, Adjustable Voltage Positioning

8 Independent Frequency Selections per

Channel (CPU/GPU)

•

Patent Pending AutoBalance™ Phase

Balancing

•

Selectable 8-Level Current Limit

3-V to 28-V Conversion Voltage Range

The BOOT voltage (V_BOOT) on the TPS51640A and

TPS59640 is 0 V. The TPS59641 is specifically

designed for a V_BOOTlevel of 1.1 V.

Two Integrated Fast FET Drivers w/Integrated

Boost FET

These controllers are packaged in a space saving,

thermally enhanced 48-pin QFN. The TPS51640A is

rated to operate from –10°C to 105°C. The

TPS59640 and TPS59641 are rated to operate

from –40°C to 105°C.
