Figure 30 CV Priority and Low Impedance Load
If it requires minimum voltage overshoot, such as supplying power to a low-voltage
processor or FPGA core, it is recommended to use CV priority mode.
7.5.4 CV Priority Mode
Under CC priority mode, the control system will initially set voltage to the set value
and set current to 0A. The current will continue to rise. During this process, the
current is always regulated, with fast current rise time and minimum overshoot.
Rush.
When supplying power to low impedance loads under CC priority mode, the power
supply will always remain in CC mode.
When supplying power to high impedance loads, high impedance cannot make
enough current flow through the load. However, the current flowing through the
high impedance load will generate high voltage. The voltage will quickly reach the set
value. In this case, CC mode is converted to CV mode, which may cause unstable
voltage control during the conversion process, and voltage overshoot.
