The STEVAL-ISA146V1 is a evaluation board from STMicroelectronics specifically designed for DC/DC & AC/DC (Off-Line) SMPS. It is intended for general purpose power conversion and constant frequency switching regulators applications such as offline SMPS, conventional converters, USB chargers and telecom applications. In particular, it is suitable for off-line SMPS applications that use the STNRGPF0N family of STMicroelectronics Power Switches (STPS).
The STEVAL-ISA146V1 evaluation board is equipped with a STNRGPF060N Power switch (STPS) and a STNRGPF050N diode. It has a voltage input range of 135Vac to 265Vac and a output voltage range of, 0V-30V with an output current of up to 2A. It is also designed to be able to provide protection against short-circuits, overvoltage and over-temperature.
The STEVAL-ISA146V1 evaluation board provides a simple and efficient solution for a range of general-purpose power applications. It features a buck converter topology with integration of the primary side control loop, secondary control loop and EMI filter. It also includes a PFC Preconditioner to reduce power losses in the input rectifier and a Synchronous Rectifier for improved efficiency.
The STEVAL-ISA146V1 evaluation board is based on the STNRGPF0N family of Power Switches from STMicroelectronics and is intended for DC/DC and AC/DC (off-line) SMPS applications. It is a constant-frequency switching regulator designed for both Continuously Current Mode Control (CCMC) and Frequency Modulated Control (FMC) operating modes.
In CCMC mode, the controller can adjust the switching frequency of the MOSFET to maintain the output current to the desired value, regardless of load or line variations. It also takes input from an external feedback signal, which allows the system to regulate to a specific load or line condition. The board can also be switched to FMC mode, which can provide exact line and load dynamic regulation of the output voltage.
The STEVAL-ISA146V1 evaluation board also integrates a Zero-Voltage Switching PFC Preconditioner to reduce the power losses in the rectifier and a synchronous-rectifier to provide improved efficiency. The board is designed to be protected against over-temperature, overvoltage and short-circuit conditions. The evaluation board is rated to work at a maximum input current of 5A and an input voltage range of 135Vdc-265Vdc. It also has a wide output voltage range of 0V-30V with an output current capability of up to 2A.
The STEVAL-ISA146V1 evaluation board is a compact and easy to use platform for exploring the capabilities of STMicroelectornics power switches and it is well suited for DC/DC and AC/DC (off-line) SMPS applications. It allows designers to quickly evaluate the different features and specifications of the power switches and efficiently design converters and SMPSs for a wide range of applications.
