Description The device is an off-line converter with an 800 V rugged power section, a PWM control, two levels of over-current protection, over-voltage 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.

Features ■ 800 V avalanche rugged power section
■ PWM operation with adjustable limiting current
■ 30 mW stand-by power at 265 Vac
■ Operating frequency:
– 60 kHz for L type
– 115 kHz for H type
■ Frequency jittering for low EMC
■ Output overvoltage protection
■ High primary current protection (2nd OCP)
■ Extra power timer for peak current management
■ On-board soft-start
■ Safe auto-restart after a fault condition
■ Hysteretic thermal shutdown

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