Abstract
A converter system is disclosed. The converter system including a system controller; a plurality of circuit elements configured to operate in response to control signals from the system controller; a bus controller configured to transmit data to a communication bus; and a plurality of power converters, each including a digital to analog converter (DAC) configured to generate an analog voltage for one or more of the circuit elements based on a digital signal on the communication bus; a digital module configured to receive digital data from the bus controller on the communication bus; and an amplifier, configured to adjust an offset according to an offset compensation code received from the digital module.

A converter system, comprising:
- a system controller;
- a plurality of circuit elements configured to operate in response to control signals from the system controller;
- a bus controller configured to transmit data to a communication bus;
- and
- a plurality of power converters, each comprising:
- a digital to analog converter (DAC) configured to generate an analog voltage for one or more of the circuit elements based on a digital signal on the communication bus;
- a digital module configured to receive digital data from the bus controller on the communication bus;
- and
- an amplifier configured to adjust an offset according to an offset compensation code received from the digital module.
