Working Principle

The working principle of SC02D24A is based on a synchronous rectification buck-boost converter. It utilizes a first-order control loop based on a voltage feedback comparator and an error amplifier with current source reference. A main switch isolates the input voltage from the output. By controlling the duty cycle of the main switch, the output voltage can be adjusted to a desired level. The input voltage, the output voltage and the duty cycle are all monitored and controlled by an internal MCU.

In addition to the voltage regulation, SC02D24A is also equipped with power factor correction (PFC) circuitry, which helps to reduce the input AC power consumption and reduce the amount of EMI interference generated by the device. This also minimizes the need for additional external EMI filters thus reducing design cost.
