Linear regulator is a individual module. Module mounted on back cooler.
Regulator is four level voltage regulator. Hardware CC/CV detector.
Controlled by STM32F337. Used 16bit delta-sigma ADC for measure voltage and current.
For measure low current used INA229.
AD5663 16bit DAC use for current and voltage setpoint.
Used fan speed proportional control for minimize noise.
Module communicate by UART ModBus.
