Working Principle

The S-85S1AB23-I6T1U uses a synchronous rectifier circuit to achieve high efficiency and low noise level. It has an integrated circuit oscillator and control circuit, which dynamically adjust the output voltage based on the input voltage. The output voltage can be adjusted in two ways. First, by changing the value of the feedback resistor, the output voltage can be adjusted to within 0.5 V increments. This allows fine-tuning of the output voltage if an exact voltage is required. Second, the output voltage can be adjusted on the fly by using the Enable pin. The Enable pin can be controlled by an external signal, so that the output voltage can be changed in response to changing conditions.

The S-85S1AB23-I6T1U also has a slew rate control circuit, which controls the rate of change of the output voltage. This helps reduce ringing and noise when the output voltage is changed. The S-85S1AB23-I6T1U also has over-current and over-temperature protection, which help protect the device from damage in the event of an over-current or over-temperature condition.
