Controllers Revamp Isolated DC-DC Converter Designs
Feb 1, 2004
The task of designing an isolated dc-dc converter for mainstream applications has been simplified in recent months by several advanced PWM controllers....
Using a Current Mode PWM Controller in Voltage Mode
Jan 1, 2004
Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM controller...
Benefits of Digital Multiphase PWM Power Control
Oct 1, 2003
Since the early 1990s, the power requirements for VCC core voltages for leading-edge processors and ASICs have become increasingly demanding, with chip...
Multiphase Technique Is Flexible and Scalable
Mar 1, 2003
Multiphase power conversion is virtually the only viable approach to handle today's multi-gigahertz microprocessors that devour 60A to 80A at 1.3V to 1.5V, and are moving toward 100A and higher with supplies of 1 V and below....
New Control Method Boosts Multiphase Bandwidth
Jan 1, 2003
As the dynamic and static load current increases, there's a need to increase the number of phases in the multiphase converter system to improve the transient performance for next-generation processors....
