Application notes cover powersupply designs. Design guidelines and technical details cover BCM converters, PRM regulators, and VTM current multipliers. Topics include creating current-sharing parallel arrays for high-power, low-voltage applications using PRM and VTM pairs, as well as design practices for powering multiple VTMs with a single PRM. One BCM application note describes basic design practices when using the BCM as an intermediate bus converter to provide a bus voltage to low-power devices.
