PI3020-00
Advanced Datasheet – Digital Control and Telemetry Device
Description
Features
The PI3020 is a Digital Control and Telemetry (DCT)
device. It provides a programmable precision
reference, high bandwidth analog error control loop
and internal analog compensation as well as precision
current sensing and optional programmed impedance
control. Moving the sensitive analog compensation
components internal to the PI3020 simplifies system
implementation and circuit layout. Industry standard
PMBus commands are supported for the reporting of
telemetry, power sequencing, or in system
programmable update or reconfiguration. A
multiplexed 12bit A/D is provided, and a precision
3.1V reference pin is also provided. The PI3020
includes the proprietary SVID control interface with
full support for server processor power VR13, and
backwards compatibility support for VR12.5 and
VR12.0 designs. Internally programmable analog
control loop architecture enables high bandwidth
linear operation with multiple zero and pole control.
The high speed linear control operation reduces the
size of the external power train filtering components,
improves power density, and enables very fast
dynamic response to line and load transients. The
PI3020 supports large input to output conversion
ratios and allows additional optimization of
PRM+VTM systems. The PI3020 also includes a PWM
output for control of a secondary rail, or the main rail.
