Description The device is an off-line converter with an 800 V avalanche ruggedness power section, a PWM
controller, user defined overcurrent limit, protection against feedback network disconnection, hysteretic thermal protection, soft start up and safe auto restart after any fault condition.

Features ■ 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
■ On-board soft-start
■ Safe auto-restart after a fault condition
■ Hysteretic thermal shutdown

Application ■ Auxiliary power supply for appliances
■ Power metering
■ LED drivers
■ SMPS for set-top boxes, DVD players and recorders
