AC-DC converters enable the conversion of an alternating current (AC) to a direct current (DC). The SPPC5351 is a highly efficient switch mode power supply (SMPS) AC-DC converter that uses a full bridge rectifier and a transformer-based inverter to provide an isolated power supply. It is designed for indoor use, and has low power dissipation, low electromagnetic interference (EMI), and low electromagnetic susceptibility (EMS).

The SPPC5351 is capable of delivering a constant voltage with a wide input voltage range. It can supply up to 45 Watts of power, and features a no-load input power consumption of less than 0.5 Watts. The input voltage may range from 85 to 265 Volts AC, while the output voltage may range from 3.3 to 24 Volts DC. Additionally, the output voltage can be adjusted with a single-turn trimmer pot. The device also features short-circuit protection, thermal shutdown, and auto Recovery.

The SPPC5351 is a flyback switched-mode power converter. It utilizes a full-bridge rectifier to convert the AC input voltage to a DC voltage. This DC voltage is then fed to a transformer, which is used to step up the voltage to the desired output voltage. The output of the transformer is then rectified, and a buck converter is used to deliver a constant DC voltage at the output. The output voltage is regulated by feedback control, which monitors the output voltage and adjusts the duty cycle of the switching transistors accordingly.

The performance of the SPPC5351 is further enhanced by its low power dissipation and low EMI and EMS. The device is protected from overvoltage, overcurrent, and short-circuit, which further boosts its reliability. The no-load power consumption of the device is less than 0.5 Watts, and the device is highly efficient, achieving an efficiency of up to 95%. Additionally, the device is RoHS (Restriction of Hazardous Substances) compliant.
