The IRDC2086-330W, a reference design featuring the IR2086S DC Bus Converter control IC and DirectFET® power MOSFET chipset is said to simplify development of 48-V input brick or embedded power supplies for networking, communications and high-end server applications. The reference design is a 48 V to 9.6 V (35 A) unregulated DC bus converter that is said to be 97-percent efficient, in a size 30-percent smaller than industry-standard quarter brick regulators. In addition, the design is said to reduce the number of powertrain components from three ICs and 14 FETs to a single IC and eight FETs. International Rectifier
