Product Description
STMicroelectronics VIPER114HSTR is an advanced high voltage switcher designed for energy-efficient off-line power conversion. It integrates a robust 800 V avalanche-rugged power MOSFET with PWM current mode control, providing reliable performance in a compact 10-pin SSOP surface-mount package.
This device supports a maximum input voltage of 30V and delivers up to 12W output power with a maximum output current of 504mA. It operates at a switching frequency of 60kHz, optimizing efficiency and minimizing external component size. The integrated HV start-up, sense-FET, error amplifier, and oscillator with jitter allow the design of compact flyback power supplies.
Highlights include pulse-skip protection to prevent flux runaway, embedded thermal shutdown, and a built-in soft-start feature that improves system reliability and longevity. The device operates over a wide temperature range from -40°C to 150°C, making it suitable for demanding industrial and electronic power management applications.
The compact SSOP package with dimensions 5mm length, 6.2mm width, and 5mm height is ideal for surface mounting on printed circuit boards with minimal space footprint. The device meets rigorous energy-saving standards by operating with very low power consumption during light load conditions.
Typical applications include buck, flyback, and buck-boost converters in power supplies for industrial machines, electronic systems, and control instrumentation. The device’s integrated features reduce the external component count and simplify power supply designs.
