ST VIPER17HN

Изолированный8,5 В ~ 23,5 В10 W

Overview

The device is an off-line converter with an 800 V rugged power section, a PWM control, two levels of overcurrent protection, overvoltage and overload protections, hysteresis thermal protection, soft-start and safe auto-restart after any fault condition removal. The burst mode operation and the device’s very low consumption 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 specifiedfor the system. The high voltage start-up circuit is embedded in the device.• 800 V avalanche rugged power section• PWM operation with frequency jittering for low EMI• Operating frequency:– 60 kHz for L type– 115 kHz for H type• 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• Hysteresis thermal shutdown• Adapters for PDA, camcorders, shavers, cellular phones, videogames• Auxiliary power supply for LCD/PDP TV, monitors, audio systems, computer, industrial systems, LED driver, No el-cap LED          driver• SMPS for set-top boxes, DVD players and recorders, white goods
