    Active Voltage Positioning Reduces Output Capacitors
    by Robert Sheehan
    INTRODUCTION
    Power supply performance, especially transient response,
    is key to meeting today’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 “active voltage positioning” 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 “active voltage positioning” (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 ...
