STMicroelectronics Power Management Demonstration Board for VIPER16LD Non-Isolated SMPS STEVAL-ISA119V1

STMicroelectronics STEVAL-ISA119V1 is a power management demonstration board for the VIPER16LD device, designed specifically for non-isolated switching mode power supplies (SMPS). This dual output buck evaluation board offers a robust solution for efficient offline high voltage conversion.

The board supports output voltage regulation through a simple voltage divider allowing precise control. VIPER16LD on board can operate with or without an external supply, enabling versatile design options. When powered externally, the board achieves very low standby power consumption of less than 50 mW at 265 Vac, making it energy efficient.

Featuring an 800 V avalanche-rugged power section, the device assures high reliability and robustness against voltage surges. The controller operates PWM at 60 kHz with frequency jittering to reduce electromagnetic interference (EMI), enhancing compliance with EMI standards.

The design incorporates an adjustable current limiting set point to protect against overcurrent conditions along with an integrated soft-start function that reduces inrush current at startup. The board also offers safe automatic restart after fault detection to improve system resilience.

Protection features include thermal shutdown with hysteresis to prevent damage during temperature rises and delayed overload protection for safer operation under adverse conditions. This evaluation board offers engineers a versatile platform for development and optimization of power management systems in industrial, commercial, and laboratory applications.
