S-85S1PD26-I8T1U Voltage Regulator Working Principle

The S-85S1PD26-I8T1U utilizes pulse width modulation (PWM) technology to reduce the input voltage to a lower voltage output. The basic circuit consists of a MOSFET switch, which switches rapidly to create an output voltage in a DC to DC converter.

The MOSFET switch is turned on and off at a high frequency. When the switch is on, the input voltage is applied to the output filter capacitor. The filter capacitor stores the energy until the switch is turned off. When the switch is turned off, the filter capacitor releases the stored energy to create the output voltage.

The current flow through the switch is proportional to the width of the switch pulse and the input voltage. The output voltage is then constantly regulated by adjusting the width of the pulse. The output voltage is constantly monitored and compared to the reference voltage. If the output voltage is too low, the pulse width is increased. If the output voltage is too high, the pulse width is decreased.

The S-85S1PD26-I8T1U offers a low output ripple of 10mV for optimal clarity of the necessary output signals. The low ripple ensures that the DC to DC converter does not cause any undesirable level changes when the circuit is set for a steady voltage output. The S-85S1PD26-I8T1U is able to maintain low ripple across an extended temperature range.
