DESCRIPTION
The DCP0105 family is a series of high efficiency, 5V
input isolated DC/DC converters. In addition to 1W
nominal galvanically isolated output power capability,
the range of DC/DCs are also fully synchronizable.
The devices feature thermal shutdown, and overload
protection is implemented via watchdog circuitry.
Advanced power-on reset techniques give superior
reset performance and the devices will start into any
capacitive load up to full power output.
The DCP0105 family is implemented in standard-
molded IC packaging, giving outlines suitable for high
volume assembly.
The FPGA can realize a more optimized Digital controller in DC/DC Converters when compare to DSPs. In this paper, based on the FPGA platform, The theoretical analysis, characteristics, simulation and design consideration are given. The methods to implement the digital DC/DC Converters have been researched. The function module, state machine of digital DC/DC controller and high resolution DPWM with Sigma-
Delta dither has been introduced. They are verified by experiments on a 20 W, 300 KHz non-isolated synchronous buck converters.
