Summary

This reference design provides an easy method to evaluate the power, and features of SMPS dsPIC® Digital Signal Controllers in high density quarter brick DC-DC converters for intermediate bus architectures(IBA). This reference design is implemented using a single dsPIC33F “GS” digital-power DSCs from Microchip that provides the full digital control of the power conversion and system management functions. As shown in this reference design the dsPIC33F ‘GS’ devices enable designers to easily and cost effectively create products using advanced switching techniques such as Phase Shift Full Bridge (PSFB) topology that lower switching losses and enable efficiencies as high as 94%. The reference design also supports the Full Bridge topology through minor hardware modifications. The Quarter brick DC to DC Converter Reference Design is royalty free when used in accordance with the licensing agreement.

This reference design works with telecom input range 36V – 76V DC and provides 12V with 200W power. Designed with planar magnetics, this reference design implements various non-linear techniques, which improves the performance and efficiency.
