Advanced Pulse Width Modulation Controller ICs for DC-DC Converters

From architecture to circuit implementation

• Broschiertes Buch

Produktbeschreibung

This book describes power management ICs to tackle
the challenges for both accurate and efficient power
delivery for today''s high performance processors.
A double-edge multi-phase low-latency pulse width
modulator IC is implemented in 0.18 um CMOS process
with 0.04 mm2 active area and demonstrates a fast
double-edge pulse width modulation scheme which is
important for achieving fast controller response for
high bandwidth applications. A multi-mode 4-phase
digital IC controller for voltage regulator
application is implemented in 0.18 um CMOS process
with 4 mm2 active area. The controller combines load
current feedforward with voltage mode feedback to
achieve fast transient response and multi-mode
control strategy improves the converter efficiency by
at least a factor of ten in light load condition. A
load-scheduled integrator array is developed in the
controller IC which improves the load transient
response when voltage regulator transitions between
continuous conduction mode and discontinuous
conduction mode.
