Implementation of microprocessor-controlled, wide-input-voltage, SMBus
This paper describes using a microprocessor to control the power-stage board of a wide-input-voltage DC/DC controller. This solution can support an input voltage of up to 55 V; a battery-charging voltage ranging from 5 to 51 V; and up to 10 A of output current in most cases. Both the hardware and software discussed in this article have been developed and tested by Texas Instruments applications staff to allow customers to quickly prototype the solution.
