S-85S1PC35-I8T1U is an integrated switching regulator control circuit with low power consumption and good noise reduction characteristics. It is integrated into a DC-DC switching regulator integrated circuit with a wide range of applications.

Application Fields:

S-85S1PC35-I8T1U is suitable for various sectors, such as personal electronics, automotive, solar cell products, LED lighting products and other fields. It is designed as a low power consumption, high efficiency DC-DC voltage regulator circuit and can be applied to a wide output voltage range and rated input voltages up to 30V. Its high precision pulsewidth modulation (PWM) output can respond quickly, enabling the circuit to enhance the system performance.

Working Principle:

The voltage regulator circuit consists of an internal PWM IC and a pulse transformer to control the output. When the circuit is in operation, the PWM IC enters a cycle and whole cycle can be divided into two states: switching state and reset state. During the switching period, the power MOSFET switches is turned on, allowing current to flow through the pulse transformer at the output stage and resulting in stored energy in the primary coil and secondary coil of the transformer. In the reset period, the power MOSFET switches is turned off, and then the stored energy in the primary and secondary coils of the transformer is released, providing a constant output voltage to the load.

Advantages:

The S-85S1PC35-I8T1U employs a variable-frequency fixed-on time (VffOT) control scheme which can significantly reduce the power consumption up to 1/3. Its high precision PWM output also offers excellent efficiency and fast response. The wide output voltage range and high surge capacity makes it ideal for a variety of different applications. Moreover, it has excellent noise reduction characteristics and can effectively reduce high frequency noise.

Conclusion:

In conclusion, the S-85S1PC35-I8T1U is an integrated DC-DC switching regulator circuit with a wide range of applications and excellent characteristics. It can respond quickly and effectively reduce high frequency noises, making it suitable for personal electronics, automotive, solar cell products, LED lighting products and other fields.
