Working Principle

The REC10-4805SRW/H2/A/M/SMD utilizes a switched mode topology to convert direct current from one voltage to another. The device uses a hetero-structure MOSFET to regulate the output voltage of the converter. The output voltage of the converter is determined by the external resistor divider which acts as the adjustment port of the converter. The converter is designed to switch the MOSFET on and off rapidly at a frequency determined by the external resistor and capacitor connected to the soft-start pin. During each cycle, the output voltage is equalized with the input voltage, and the output voltage will adjust accordingly. The output voltage of the converter is regulated by the percentage of on-time and off-time. This process continues until the desired output voltage is reached. The converter also employs protection circuits to ensure safe and efficient operation.

In conclusion, the REC10-4805SRW/H2/A/M/SMD is an efficient and cost-effective DC-DC converter suitable for a wide range of applications.
