Working principle

The CSS28048/M AC to DC converter works using a current mode PWM control circuit with an integrated linear fluctuation compensation (LFC) circuit. In this converter, a transformer is used to step down the AC input voltage to a lower DC voltage, which is then rectified and filtered before being compared with the reference voltage of the PWM control circuit. This signal is then used to adjust the power output of the circuit. The linear fluctuation compensation (LFC) circuit helps to stabilize the output voltage during changes in line voltage and current.

The PWM control circuit also provides protection against over-current, overload, reverse polarity, and over temperature conditions. Additionally, the CSS28048/M converter can be designed to provide a reliable and stable power supply for a wide range of applications that require a low output voltage and current. The efficiency of the power conversion is also improved due to the low transformer power loss.
