Off-line high voltage converters

Features

■ 800 V avalanche rugged power section

■ Quasi-resonant (QR) control for valley

switching operation

SO16 narrow

SO 16

DIP-7

■ Standby power < 50 mW at 265 Vac

■ Limiting current with adjustable set point

Description

■ Adjustable and accurate overvoltage

protection

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

■ On-board soft-start

■ Safe auto-restart after a fault condition

■ Hysteretic thermal shutdown

protection, soft-start and safe auto-restart after

any fault condition removal. Burst mode operation

and device very low consumption helps to meet

the standby energy saving regulations. The quasi-

resonant feature reduces EMI filter cost. Brown-

out and brown-in 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.

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
