1050 V High voltage converter
Data brief Description
The device is an offline converter with a 1050 V avalanche rugged 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. Advance frequency jittering reduces EMI filter cost. Burst mode operation and the device‘s very
Features
low consumption both help to meet the standard set by energy saving regulations. 1050 V avalanche rugged power section Current mode PWM controller Embedded high voltage startup and sense FET Drain current limitation (OCP) Standby power < 30 mW at 230 VAC Jittered switching frequency (60 kHz ± 4 kHz) for low EMI Embedded error amplifier for non-isolated SMPS On-board soft-start Safe auto-restart after a fault condition Hysteretic thermal shutdown
Applications
SMPS for energy metering Auxiliary power supplies for 3-phase input industrial systems LED driver
