, including a power MOSFET, high-voltage start circuitry, and low power consumption. The Si9114A controller pushes the limits for high-frequency power conversion by further reducing delay times and adding additional features
. As a result, dc-to-dc converters can be designed for frequencies up to 1 MHz with simple PWM topologies instead of the plex resonant ones. S reduce the size of energy storage ponents S increase reliability by using ceramic capacitors S produce an all-surface-mount assembly solution S lower system costs S simplify the implementation of a distributed power architecture. Traditionally, distributed power has been regarded as costly and impractical to implement due to the high cost of local power conversion and the perceived plexity of resonant power supplies. But these decision criteria are now being changed by the availability of small-outline control ICs, LITTLE FOOTr MOSFETs, ceramic capacitors, and new magnetic ponents.
