Efficient power management is an important design element enabling systems developers to overcome increasing demands for compact size, low-power operation and improved functionality. In addition, many electronics systems require low multiple power rails and supply solutions that need to address the few milliamps needed for standby supplies as well as the over 100 A requirements for application-specific integrated circuit (ASIC) voltage regulators. Low-voltage processors, digital signal processors (DSPs), and double data rate (DDR) memories also impose stringent requirements on the power supply.
