Working Principle

The STCH02 offline switcher is based on a simple PFC (Power Factor Correction) topology that has the additional functionality of integrating an inverted PFC circuit block and an isolated DC-DC switching converter. The integration of an inverted PFC circuit block ensures that the input voltage of the switcher is always maintained at a constant level, even when subjected to varying line inputs. This is beneficial as it helps to ensure that the output voltage of the switcher is consistent, regardless of the input voltage.

The isolated DC-DC switching converter ensures that the output voltage of the switcher is isolated from the input voltage and is not affected by input voltage fluctuations. The output voltage of the switcher is regulated by an error amplifier and loop feedback signals, which allows for a constant output voltage even when subject to varying input conditions. The STCH02 also provides protection against input overvoltage, output overvoltage and output overcurrent conditions, ensuring the safe operation of the switcher.

Conclusion

The STCH02 offline switcher from STMicroelectronics is an ideal solution for powering a wide range of mains powered applications. The switcher offers a simple, yet highly efficient and robust solution for providing an isolated output voltage from isolated or non-isolated input power sources. The switcher is capable of taking input voltages ranging from 1.2V to 600V and providing a regulated output voltage of up to 5V, making it an ideal solution for a wide range of applications.
