The presented 300 W Ultra−high Power Density Adapter (UHPD) evaluation board demonstrates ON Semiconductor’s high-performance controllers, drivers and discrete semiconductor content capabilities that enable efficient UHPD designs implementation. This reference design includes the Synchronous PFC boost converter which is operating in the Discontinuous Conduction or Critical Conduction Mode (DCM/...
Gallium Nitride semiconductors allow designers to operate at higher frequencies and voltages than their silicon counterparts, enabling power management systems that are smaller and more efficient. These new designs also require capacitors that can operate at these higher frequencies and provide stable performance at the voltages that GaN devices typically operate at.
