6 Power Management (6 to 60-V DC Power Supply)

A power-management block involves converting AC to DC and stepping down the DC levels as required by the BLDC motor. TI has a wide range of high-voltage input DC-DC converters such as the TPS54060, TPS54560, and TPS54361 devices that can be used in this application.
