DATASHEET
Description
The IDTP62000 is a multiphase interleaved synchronous
buck controller ideal for personal computer applications
where high efficiency and high power density are required.
It contains three integrated MOSFET driver pairs to enable
a 3-phase regulator solution that allows load currents up to
150A for low voltage microprocessor power requirements. It
also provides a 4th PWM output phase to drive a low cost
IDTP67111 single phase driver to become a full 4 phase
solution.
The VID logic can be configured for applications compliant
to the Intel VR11.1, Intel VR10 or AMD PVI/SVI
specifications.
The maximum number of operating phases (2/3/4) is pin
programmable, and depending on output loading
conditions, the active number of phases can be dynamically
reduced. The Dynamic Efficiency Control (DEC) feature
enables all configured phases when full current output is
required, and dynamically reduces the number of active
phases at reduced current levels. Combined with Dynamic
Voltage Change (DVC) and Dynamic Frequency Change
(DFC) this allows full output current while also providing for
more efficient operation at lower power output.
The design allows a positive or negative offset to the VID
voltage being used for regulation and supports both
external, resistor based, and internal, register based,
programming of this offset voltage.
An internal soft start (SS) is included in the design to
prevent large inrush currents at power on. The ramp rate of
the soft start can be adjusted with an external resistor.
A DCR current sensing method combined with rapid
transient response architecture enables superior phase
current matching, accurate current limit and precise
load-line control. Furthermore, this device incorporates a
proprietary scheme for fast and accurate
transient-response performance, as well as precise load
sharing.
