VIPER17 is an offline high voltage 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, thermal shutdown, and brown‑out. It is intended for adapters, auxiliary power supplies, and SMPS applications in consumer electronics and industrial equipment.
The document provides a block diagram, pin‑out description, electrical ratings, typical performance curves, and mechanical data for DIP‑7 and tube packages. Key specifications include maximum drain‑to‑source voltage, pulse drain current, power dissipation, and operating temperature range.
| Maximum drain‑to‑source voltage | 800 V |
|---|---|
| Repetitive avalanche energy | 2 mJ |
| Pulse drain current | 2.5 A |
| Power dissipation (Ta < 50 °C) | 1 W |
| Operating junction temperature range | -40 °C to 150 °C |
| Standby power consumption | < 50 mW at 265 Vac |
| Operating frequency (L type) | 60 kHz |
The standby power consumption is less than 50 mW when operating at 265 Vac.
The L‑type operates at 60 kHz, while the H‑type operates at 115 kHz.
The device can tolerate up to 800 V drain‑to‑source voltage.
