The STCH03TR is a highly integrated AC/DC converter of PMIC – AC DC Converters, Offline Switchers, which is typically used to provide an isolated 3.3V output from a non-isolated, high-voltage input of 48V. Compared to traditional offline switcher systems, the STCH03TR provides the same quality output but with enhanced design efficiency, better reliability and cooler operating temperatures.The operating principle of the STCH03TR is based on the Fixed Off-Time Control topology, which allows the device to operate stably even under fluctuating load conditions with fast response time. The STCH03TR also features a high efficiency of up to 97.5% with a low standby power of only 0.266W. In addition, the device is fully compliant with the latest IEC61000-3-2/-3-3 standards and EN55011/CISPR11, which makes it ideal for use in applications such as industrial control, factory automation, office equipment, solar power inverters and telecom systems.

The STCH03TR is available in a range of package options including chip scale, DIP, SOP and custom semiconductor packages. In addition, the device is equipped with an internal thermal overload protection, a soft-start function and an integrated fault flag. The device is also capable of working with a wide range of input voltages from 45V to 460V. Moreover, the STCH03TR comes with a wide range of adjustable features, including output voltage, current limit, start-up time and power loss protection. All these features make the STCH03TR one of the most cost-effective and reliable AC/DC converters available in today’s market.

In terms of application field, the STCH03TR is suitable for use in industrial, office and telecom industries, where it can provide reliable and clean power to a variety of applications. In the industrial field, the STCH03TR can be used in security and surveillance systems, factory automation, machine tool manufacturing, motor drives and robotics.
