Application Note 9862
High dV/dt spikes present in the output voltage waveform
under highly dynamic load application (high dI/dt) are due to
the ESR and the ESL of the output capacitance. These
spikes coincide with the transient load’s rising and falling
edges, and decreasing their amplitude can be achieved by
using lower ESR/ESL output capacitors (such as surface-
mount tantalum capacitors), and/or the addition of more
ceramic capacitors, which have inherently low ESR/ESL.
The addition of more input-side capacitance and decreasing
the input-side capacitor banks’ ESR can also help in
situations where the input-side ripple is affecting the output
regulation. Such an example is excessive ATX 3.3V ripple
reducing the collector-to-emitter voltage available for Q2
(2.5V setting), and thus inducing an output droop component
- in such instance, the addition of input-side capacitance and
reduction of the ESR component can reduce the output
excursion.
Conclusion
The HIP6500B and HIP6502B are sophisticated integrated
circuits that envelop all the required circuitry for ACPI
implementation in computer motherboards and computer
systems. The circuits employ intelligent switching methods
for smooth power plane transitions, noise immunity circuits
for nuisance trip avoidance, and a direct interface to the
south bridge and logical circuitry for simplified control and
configuration.
