The STEVAL-ISA021V1 is a cost-effective, reliable evaluation board designed for use in DC/DC & AC/DC (off-line) SMPS (Switch Mode Power Supply) applications. This evaluation board serves as a platform for customers to evaluate the features and performance of ST’s Microchip brand energy-efficient ICs for SMPS. This evaluation board is both reliable and highly versatile, making it ideal for mainstream applications in consumer, industrial, computer and automotive markets.

The evaluation board has multiple features that make it a perfect fit for a variety of applications. The board is provided with a buck-boost converter circuit and also a direct PFC synthesizer, which is capable of achieving high efficiency and reduce losses in the output. It also features an accurate and low-noise voltage supervision circuit, making it suitable for low voltage operation.

The board has both buck and boost mode of operation. In the buck-mode, the input voltage is above the output voltage, while in the boost-mode, the input voltage is below the output voltage. It also has protections against short circuit, overload, over-voltage and under-voltage.

The board is based on a sophisticated controller which utilizes high-precision references with programmable LED current senses to ensure system accuracy and stability. This controller also offers a wide range of protection features, such as cycle-by-cycle current limit, dual mode over-current protection, thermal protection, and short circuit protection. This makes it an ideal choice for power applications, where high efficiency and stringent precision requirements are paramount.

The evaluation board utilizes a synchronous buck-boost topology with two FETs (field effect transistors) in order to minimize the number of components. This reduces the overall cost of the system and the complexity of the design, in addition to providing greater efficiency than traditional buck-boost designs. The synchronous structure also helps to significantly reduce EMI and reduce switching losses.

The STEVAL-ISA021V1 has extremely small component footprints due to its high integration, allowing the board to be used within compact applications. This board can operate from a range of input voltages, up to 42V DC.

The evaluation board provides a user-friendly graphical user interface as its control point and monitoring tool. The user can easily customize settings for the buck-boost topology output as well as the operation of the PFC synthesizer, such as the current limit, ramp up time, output voltage, switching frequency, latency time, and soft-start time. This makes the STEVAL-ISA021V1 a highly flexible device suitable for multiple applications.

Due to its high level of integration, the evaluation board can be used in a wide range of applications that require efficient performance as well as accuracy and stability. Its features make it an ideal choice for testing and evaluating DC/DC & AC/DC (off-line) SMPS applications.
