Patent ID: 8901774

Claim:
A power supply system, comprising: a plurality of power blocks, each power block adapted to convey power to a respective load responsive to a respective pulse width modulation (PWM) control signal; and a digital power manager adapted to (1) program operating parameters and receive monitoring data of said plurality of power blocks using input/output circuitry integrated in said digital power manager, and (2) generate the PWM control signals of all the power blocks in response to said monitoring data so as to implement closed-loop control of the power conveyed by each of said plurality of power blocks, wherein said digital power manager further comprises a non-volatile memory containing a plurality of registers, said plurality of registers including: an application register containing data values (1) programming operation of said power blocks and (2) monitoring state of said power blocks; a configuration register containing data values defining a configuration of said power supply system; a boot register containing data values reflecting base layer operation to said non-volatile memory; buffers including an application buffer, a configuration buffer, and a boot buffer containing new firmware data; a user-definable space; and a logging data space containing field information in the event of failure.
