Working Principle of V24C24C50B

The V24C24C50B utilizes a synchronous buck topology to provide either step-down or step-up voltage conversion, depending on the operating mode. The primary windings of the transformer are connected in series with the input voltage, and the secondary windings are connected in series with the output voltage. The primary current, i.e., the input current, is compared to a reference signal and used to adjust the duty cycle of an internal switch, which controls the output voltage. The secondary current, i.e., the output current, is regulated by an internal current sense circuit. When the operating mode is set to continuous current mode (CCM), the secondary current is limited to provide high power efficiency. When the operating mode is set to discontinuous current mode (DCM), the secondary current is not limited, and the output voltage is regulated by controlling the inductor current.

In addition, the V24C24C50B utilizes adaptive feed forward control to provide a fast response to load changes and minimize the output voltage ripple. Adaptive feed forward control is enabled by a feedback loop that constantly adjusts the operating frequency to provide fast response and stable regulation at high load current. With adaptive feed forward control, the V24C24C50B can operate at up to 1MHz, while still providing stable operation.
