The VE4022 is an Emerson controller. It uses current mode control, that is, the error amplifier output signal is compared with the sampled inductor peak current, so as to control the duty cycle of the output pulse, so that the output inductor peak current changes with the error voltage.
The functions of VE4022 mainly include current control and voltage control. It uses current mode control to compare the output signal of the error amplifier with the peak inductance current sampled, so as to control the duty cycle of the output pulse, so that the peak inductance current of the output changes with the change of the error voltage. In addition, it has a voltage control mode to adjust the output voltage.
The VE4022 features high stability, high precision and low power consumption. It adopts advanced control algorithm, which can realize high-precision current and voltage control and ensure the stable operation of the equipment. At the same time, it also has a low-power design, which can reduce energy consumption and improve the operation efficiency of the equipment.
