VIPER26LDTR ST AC-DC Controllers

The VIPER26LDTR is a low-power offline switched-mode power supply primary switcher from STMicroelectronics, integrating an 800V avalanche rugged power MOSFET with PWM controller in an 16-pin SOIC package. For selection, verify input from 85V to 265V AC, 800V MOSFET rating, 12W peak output power (wide range) or 20W (single range), fixed 60kHz switching frequency, and -40°C to +150°C operation. Features include current-mode control, auto-restart protection, hysteretic thermal shutdown, frequency jittering for EMI reduction, and adjustable current limit. Ideal for low-cost AC-DC adapters, auxiliary power supplies, LED drivers, battery chargers, and home appliances requiring compact offline power conversion.
