Active Voltage Positioning Reduces Output Capacitors
by Robert Sheehan
INTRODUCTION
Power supply performance, especially transient response,
is key to meeting todayвЂ™s demands for low voltage, high
current microprocessor power. In an effort to minimize
the voltage deviation during a load step, a technique that
has recently been coined вЂњactive voltage positioningвЂќ is
generating substantial interest and gaining popularity in
the portable computer market. The benefits include lower
peak-to-peak output voltage deviation for a given load
step, without having to increase the output filter capacitance. Alternatively, the output filter capacitance can be
reduced while maintaining the same peak-to-peak transient response.
BASIC PRINCIPLE
The term вЂњactive voltage positioningвЂќ (AVP) refers to
setting the power supply output voltage at a point that is
dependent on the load current. At minimum load, the
output voltage is set to a slightly higher than nominal level.
At full load, the output voltage is set to a slightly lower than
nominal level. Effectively, the DC load regulation is
degraded, but the load transient voltage deviation will be …

Supply Meets Intel Mobile Voltage
by Wei Chen, Peter
Positioning Requirements
Guan and David Chen Introduction
The increasing demand for computing power in notebook computers has
driven up CPU clock frequency and
supply currents significantly. Meanwhile, supply voltages have quickly
decreased as CPUs migrated to finer
line-width processes. As the CPU clock
frequency exceeds 1GHz, the core
supply current has for the first time
surpassed 20A and the minimum
supply voltage has dropped below 1V.
Most of the forthcoming mobile CPUs
call for core supply currents as high
as 25A. In some cases, the supply
current could exceed 30A. The Intel
Mobile Voltage Positioning (IMVP)
specs have been enacted to deal with
these new mobile processor power
requirements. Linear TechnologyвЂ™s new LTC3714
and LTC3716 controllers are designed …
