Working Principle of the S-8366AAABA-M5T1S2

The working principle of the S-8366AAABA-M5T1S2 is based on the concept of a DC to DC converter. To be specific, it utilizes the principle of peak current mode control to control the converter switch in regulating the output voltage. The peak current mode control is a closed-loop control system, which enables the S-8366AAABA-M5T1S2 to adjust the output voltage in response to the fluctuations in input voltage. The output voltage is not affected by changes in load or line variations.

The peak current mode control works as follows: When the input voltage increases, the peak current mode control increases the duty cycle of the high-side MOSFET switch and the low-side diode switch. This increases the voltage across the output capacitor, thus increasing the output voltage. Conversely, when the input voltage decreases, the duty cycle of the switches decreases, lowering the output voltage.
