Power Solutions for Freescale QorIQ Processors - Layerscape and T-series
QorIQ T-series Voltage Accuracy
The new T-series family of QorIQ processors from Freescale demand the highest accuracy voltage regulators in order to maximize
their performance. The T-series moves the bar from ±5% to a mere ±3% total allowable tolerance including DC, AC, ripple and
transient. Only International Rectifier’s family of Digital Controllers are qualified to meet these challenging specifications.
T4240 Load step (37.5A – 53.5A) with IR3565B
Voltage Specifications:
• Total voltage tolerance
±30mV
• Overshoot excursions < 50mV okay
• Current step Slew rate 12A/µs
• Vboot = 1.05V
• VID Range: 0.975V – 1.025V
Vmin = 1.0250V
Droop ~ 25mV
Margin = 5mV
TOB = ± 30mV
T4240 Load Release (53.5A – 37.5A) with IR3565B
Vmax = 1.079V
Overshoot ~ 29.6mV
Margin = 1mV
IR’s digital controllers are specifically
optimized to utilize non-linear closed
loop feedback and predictive control
to meet the challenging QorIQ T-series
transient specifications. For smaller
transients and for steady state operation,
IR’s digital controllers default back to fixed
frequency, linear voltage mode control for
reliable, predictable operation.
Digital Bus Control
TOB = ± 30mV
The output voltage settings of IR’s digital
controllers are dynamically controlled via
a digital interface to the host processor.
These voltage settings are optimized to
ensure that the installed QorIQ T-series
processor operates at its maximum
performance within allowed performance/
sleep states.
