Fonctionnalités et applications

ST aims to be the leader in multimedia convergence applications and power solutions, offering one of the world’s broadest product portfolios, including application-specific products containing a large proprietary IP content and multi-segment products that range from discrete devices to high-performance microcontrollers, secure smart card chips and MEMS (Micro-Electro-Mechanical Systems) devices.

The VIPER27HN is an off-line converter with an 800 V rugged power section, a PWM control, two levels
of over-current protection, overvoltage and overload protections, hysteretic thermal protection, soft-start and safe auto-restart after any fault condition removal. Burst mode operation and device very low consumption help to meet the standby energy saving regulations.
Advance frequency jittering reduces EMI filter cost. Brown-out function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. The high voltage start-up circuit is embedded in the device.

 

Operating frequency:

  • 60 kHz for L type
  • 115 kHz for H type

 Features

  • 800 V avalanche rugged power section
  • PWM operation with frequency jittering for low EMI
  • Standby power < 50 mW at 265 Vac
  • Limiting current with adjustable set point
  • Adjustable and accurate overvoltage protection 
  • On-board soft-start 
  • Safe auto-restart after a fault condition 
  • Hysteretic thermal shutdown

Application:

  • Auxiliary power supply for consumer and home equipments 
  • ATX auxiliary power supply
  • Low / medium power AC-DC adapters
  • SMPS for set-top boxes, DVD players and recorders, white goods

The VIPER27HN is a 115 kHz Off-line Converter in a DIP-7 Package.
