VIPER17 is an off-line converter with an 800 V rugged power section, a PWM control, two levels of over current protection, over voltage and overload protections, hysteretic thermal protection, soft-start and safe auto-restart after any fault condition removal.
The VIPER17 is an off‑line high‑voltage converter featuring an 800 V avalanche‑rated power section, PWM operation with frequency jittering for low EMI, and a range of protection functions such as over‑current, over‑voltage, brown‑out, and thermal shutdown. It is intended for adapters, auxiliary power supplies, set‑top boxes, DVD players, and other industrial or consumer electronics.
The document provides a block diagram, pin descriptions, electrical ratings, typical power figures, and detailed specifications for the power, supply, controller, and oscillator sections. Package options include DIP‑7 and tube formats, with mechanical data and revision history included.
