VIPER50A** is a high-voltage converter IC manufactured by **STMicroelectronics (ST)**.

The VIPER50A is a high-voltage converter IC manufactured by STMicroelectronics (ST).

Specifications:

  • Input Voltage Range: 8V to 38V (DC)
  • Output Power: Up to 10W (depending on configuration)
  • Switching Frequency: 60 kHz (fixed)
  • Integrated Power MOSFET: 700V breakdown voltage
  • Current Sense Threshold: Adjustable via external resistor
  • Operating Temperature Range: -40°C to +150°C
  • Package: SO-8 (DIP-8 also available)

Descriptions:

The VIPER50A is a monolithic switch-mode power supply (SMPS) controller with an integrated high-voltage power MOSFET. It is designed for offline flyback and buck converter applications, providing efficient power conversion with minimal external components.

Features:

  • High-Voltage Startup Circuit: Eliminates need for external startup resistor
  • PWM Current-Mode Control: Ensures stable operation
  • Built-in Soft-Start: Reduces inrush current
  • Overvoltage Protection (OVP): Protects against output voltage spikes
  • Thermal Shutdown: Prevents overheating
  • Undervoltage Lockout (UVLO): Ensures proper startup conditions

The VIPER50A is commonly used in AC/DC adapters, auxiliary power supplies, and industrial power systems.
