Working Principle

The S-85S1PD07-I8T1U uses a buck switching regulator designed with an internal oscillator producing the clock frequency of the output voltage and the cycle frequency of internal switches. The primary advantage of using a switching regulator is that it is far more efficient than linear regulators because it can operate in low switch on and off times without losing much energy in the process.

The regulator uses a PWM (pulse-width-modulation) control circuit to switch on or off the MOSFET switch at a frequency determined by the internal oscillator. The duty cycle of the PWM control circuit determines the average voltage that reaches the output terminal. When the duty cycle is set to 100%, the output voltage would be the same as the input voltage, whereas when the duty cycle is set to 0%, the output voltage will be 0V.

The S-85S1PD07-I8T1U regulator also implements an autoramp soft-start which allows for a more gradual start of power up and a current limit protection circuit which provides over-current protection for each output. Additionally, the voltage regulation can also be configured to closely match the input voltage via the use of a relative voltage tracking circuit.

Application Areas

The S-85S1PD07-I8T1U switching regulator has a wide range of applications, primarily in the area of power supply design. It can be used to efficiently deliver renewable energy sources from solar panels or wind turbines, to provide regulated voltages for microprocessors, to regulate LED lighting circuits and many other power management applications.

In addition, the S-85S1PD07-I8T1U regulator can also be used in the power supply industry, where it can be used in hundreds of different configurations, or customized to meet the specific requirements of a product.
