Description
1. VIPER25HN Description:
The device is an off-line converter with an 800 V rugged power section, a PWM control, double levels of overcurrent 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. The quasi-resonant feature reduces EMI filter cost. Brownout and brown-in function protect 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.
2. VIPER25HN Features:
■ 800 V avalanche rugged power section
■ Quasi-resonant (QR) control for valley switching operation
■ 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
3. VIPER25HN Applications:
■ Adapters for PDA, camcorders, shavers, cellular phones, cordless phones, videogames
■ Auxiliary power supply for LCD/PDP TV, monitors, audio systems, computer, industrial systems, LED driver, No el-cap LED driver, utility power meter
■ SMPS for set-top boxes, DVD players and recorders, white goods
