STMicroelectronics Evaluation Board Buck Converter STEVAL-ISA116V1 5W Dual-Output Wide-Input Voltage Converter for VIPER26LD

STMicroelectronics STEVAL-ISA116V1 is a high-performance evaluation board featuring a buck converter tailored for power supply development and testing. The board utilizes the VIPER26LD device, a 12W high voltage, energy-saving VIPerPlus converter with advanced protective features.

This evaluation board supports a wide universal input mains voltage range from 80 to 280 VAC at standard frequencies of 45 to 65 Hz, making it versatile for different power environments. It provides dual-output voltages: a primary output of 16V at 300mA continuous current and a secondary regulated 5V output through an onboard LDO regulator.

The VIPER26LD featured device ensures robust performance with an 800V avalanche-rugged power section, PWM operation at 60 kHz with frequency jittering to minimize electromagnetic interference, and adjustable current limiting for safety. Additional protective features include on-board soft-start, safe automatic restart after fault events such as overloads or overheating, and low standby power consumption below 100mW at 265 VAC.

The board is fully protected against faults such as overload, feedback disconnection, and overheating, enhancing reliability during development and testing phases. Its EMI emissions conform to the EN55022-Class-B standard, ensuring compliance with regulatory requirements.

This evaluation board is ideal for engineers, researchers, and developers involved in power management, motor control, and robotics developments, offering a reliable platform for prototype validation and experimentation.
