Introduction
The IDTP62000 is a 2/3/4 phase PWM control IC that is compliant with Intel VR10.x, VR11.x, and AMD PVI/SVI CPU power
specifications. The IDTP62000 integrates three MOSFET gate drivers to minimize total solution size, parts count, and cost.
Four phase operation is supported with the addition of an IDTP67111 single phase driver IC.
The IDTP62000 includes many features and capabilities in addition those required by Intel and AMD CPUs. Proprietary
Hypergear dynamic control provides programmable scaling of CPU voltage and clock frequency to enable system level
performance and efficiency improvements. Complete Hypergear implementation includes an IDT SCPC (system clock
power console) IC and related software. Programmable Dynamic Voltage Control (DVC) and Dynamic Frequency Control
(DFC) allow performance and power consumption to be optimized as a function of load CPU current. Dynamic Efficiency
Control (DEC) enables all configured phases to operate when full current output is required and dynamically reduces the
number of active phases at reduced current levels.
An SMBus interface allows programming of IC configuration parameters and provides diagnostic and operational telemetry
data to the host system. The output voltage can be offset either in a positive or negative manner using a single external
resistor or by programming through the SMBUS interface. The IDTP62000 device contains an advanced control loop
algorithm that allows all phases to respond to load steps to minimize output capacitacnce.
The IDTP62000 can operate in stand-alone mode or it can be one part of a two chipset solution for implementing a high
performance, energy saving, computing system. The IDTP62000 PWM controller and 9CPS4592 clock generator
coordinate adjustments to the output voltage with changes in the clock frequency to optimize system performance. Figure
13 provdes a simplified view of this system.
