Evaluation Boards – DC/DC & AC/DC (Off-Line) SMPS

The STEVAL-ISA048V1 is an evaluation board designed by the STMicroelectronics team. The board is able to provide power from 8V to 50V DC for a wide variety of applications. It is ideal for the evaluation of SMPS devices such as high-efficiency synchronous DC/DC or AC/DC converters, digital power controllers and point of load converters.

Application Field and Working Principle

The STEVAL-ISA048V1 provides up to 10W of output power with a maximum input voltage of 50V. The evaluation board can be used for a wide variety of applications including consumer electronics, automotive, automotive battery charging, industrial and medical applications. It is also suitable for applications involving small power systems such as microprocessor cores, FPGAs and ASICs.The STEVAL-ISA048V1 is based on an open loop concept working without any feedback. This means that the output is maintained within a pre-defined error band. An integrated current limiter further assists in the prevention of overloading the system. The device has a wide input range and can deliver output power to a wide variety of loads.In addition to the open loop concept, the evaluation board also features passive PWM control technology. This technology is able to automatically adjust switching frequency for output current and voltage regulation. The board also offers up to 2A load current in a tiny SOT-23-6L package. The device is also able to deliver up to 5V/2.5A with an adjustable output voltage range of 0.8 - 15V. The device can also be used for low-power pre-regulators for offline systems such as LED lighting drivers, switching power supplies and DC/DC converters. For safety features, the evaluation board is equipped with protection circuits consisting of over temperature, over current and short-circuit protections. The isolation voltage between input and output is 1000V DC. The board comes with an open-frame construction and high thermal conductivity to ensure optimal performance.

Conclusion

The STEVAL-ISA048V1 provides a compact and low-cost platform for evaluating DC/DC and AC/DC SMPS devices. The device offers an adjustable output voltage range of 0.8-15V and up to 2A load current. It is also capable of delivering up to 10W output power with a 50V maximum input. The evaluation board is also equipped with protection circuits to minimize risks during operation.
